[行业软件]Siemens Simcenter FEMAP 2021.2 MP2 with NX Nastran [复制链接]

The Siemens Digital Industries Software development team is pleased to announce the availability of Simcenter Femap 2021.2 MP2. This release provides a new features and corrections that will help stability and productivity across the simulation workflow.

Geometry
- Corrected issue which caused individual solids to not be Boolean added together one at a time if the Geometry, Solid, Add command failed when attempting to Boolean add more than two solids together.
Graphics
- Corrected issue where beam elements with a trapezoidal tube cross sections were not being drawn in the correct place. This made the stress locations appear slightly incorrect, but they were actually correct and it was the cross section being drawn in the incorrect location.
- Corrected issue where Nastran General Matrix elements were not correctly included in calculation of the model box when using certain commands on the View, Autoscale menu.
- Corrected issue where nodes which had been hidden by Draw/Erase toolbar and/or the Visibility check boxes in the Model Info Tree and Visibility dialog box could still be selected when the New Picking option was on in File, Preferences.
Performance Graphics
- Corrected issue where Box, Circle, Polygon, and Freehand picking did not select nodes if the Nodes On check box was enabled on the Element/Material/Property tabs of Visibility dialog box.
User Interface - General
- Corrected issue which caused Femap to become unresponsive if solution frequencies were selected in subcases via the response frequency list and the File, Rebuild command was later used on the model (PR# 10109314).
Interfaces - Nastran
- Corrected issue that could cause Femap to become unresponsive when writing Nastran BLSEG edge contact or slide line elements where the edge nodes are connected to unsupported element topologies, such as Rigid elements.
Interfaces - Simcenter Nastran
- Corrected issue which prevented contact parameters other than PENN, PENT, and PENTYPE from being written to the BCTPARM bulk data entry when a connection property was specified for the Gaps as Contact option in the NASTRAN Bulk Data Options dialog box in the Analysis Set Manager.
- Corrected issue which caused the “MPC” case control command to not be written for SOL401/SOL402 when the Constraint Equations drop-down in the Boundary Conditions dialog box is set to “0..From Constraint Set” (PR# 10082779).
Interfaces - ANSYS
- Corrected issue reading and writing parabolic elements which did not have all midside nodes defined (i.e., only certain midside nodes were defined on an element).
- Corrected issue reading Ansys UNBL descriptor from some commands.
Properties
- Corrected issue which forced the top dimension of Wide Flange (I-beam), trapezoidal, and trapezoidal tube cross-sections used for Beam Properties to be smaller than the bottom dimension (PR# 10081554).
Meshing
- Corrected issue which caused Femap to become unresponsive when attempting to set a mesh size of a surface which referenced corrupt geometry. While the mesh sizing may not come out as expected, Femap will continue to run and cleanup of the corrupt geometry can be attempted.
Output and Post-Processing
- Corrected issue that could cause the Model, Output, Transform command to fail when transforming output in the newly created output vectors. This would only occur in some rare cases when global ply IDs were used. In all cases, the laminate Failure Indices output was improperly stored to invalid output vector IDs which would cause the failure (PR# 10050427).
Groups and Layers
- Corrected issue where New Picking is allowing curves and surfaces to be picked when they are only being displayed as part of solids which currently reside in a group, by removing code that was incorrectly implemented to make curves and surfaces on solids in groups follow the solid visibility switch (PR# 10025208).
JT Files
- Corrected issue where loads or boundary conditions that point directly into or out of the screen (i.e., directly towards or away from the user) are not being drawn correctly in JT file output.
API
- Corrected an issue that was introduced in v2021.1 that prevented batch file (*.bat) from being run from the User Tools menu on the Custom and User Tools Toolbar (PR# 10107155).
Faceted Geometry Support and Body Mesher Technology
With this release, Femap adds support for convergent modeling, allowing users to import/export, edit, and mesh geometry composed of triangular facets alongside more traditional Parasolid boundary (B-Rep) geometry. The ability to mesh faceted geometry in Femap is possible thanks to the new Body Mesher Technology, which leverages remeshing capabilities from STAR-CCM+ to generate high-quality meshes on complex surfaces that would be challenging and tedious to mesh with traditional workflows.

Updates and Enhancements


Connection Properties, Regions, and Connectors
- Added Check for Connection to Internal Edges option to Connect, Automatic command, which is only available when Edge - Edge is enabled in the Connection Types section of the Auto Detection Options for Connections dialog box. When enabled, allows connections to be automatically created between any combination of free edges an internal edges (i.e., non-free edges) of surfaces (sheet solids), solids, and general bodies which are considered coincident based on the value specified for Tolerance in the Detection Options section. If disabled, which is the default, no connections will be made between any edge and any internal edge.
- Added Surfaces to the Output section for Connection Regions. Only available when Defined By is set to Surfaces and currently only used by MSC Nastran.
- Updated the Connection Region Options dialog box to have three tabs: Simcenter Nastran, MSC Nastran, and ABAQUS. The options on the Simcenter Nastran and ABAQUS tabs were available in previous versions of FEMAP, but all of the options on the MSC Nastran tab other than Friction Value (FRIC) are new for 2021.1.
- Added Norm Scale Fac (SFNPNLT) and Tang Scale Fac (SFTPNLT) options to Contact section of MSC Nastran Advanced Contact Options dialog box accessed by the Advanced Options button on the MSC Nastran tab.
- Added Cohesive Options button to Glue Break section of MSC Nastran Advanced Contact Options dialog box accessed by the Advanced Options button on the MSC Nastran tab.

User Interface - General
- Added functionality to hide the list of entity ranges in the standard selection dialog box to improve performance when more than 1000 unique ID ranges have been selected. Once more then 1000 “unique ID ranges” are selected, the list of selected entities is replaced by text stating “(number of unique ranges) Ranges Selected” and “Show List>>>”. To display the entire list of ranges, click anywhere in the list area. To hide the list again, click the Hide List button which appears to the left of the list area.
- Added the Match Color^ button menu to the Color Palette, which selects a color by matching the color of an existing entity.
- Improved handling of “repeated error messages” to catch cases where multiple errors were repeated in a pattern. This can dramatically improve import times of invalid or incomplete Nastran models.
- Enhanced performance of picking, especially front picking (up to 15 times faster) and area picking (up to 10 times faster), when using the New Picking option on the Graphics tab in the Preferences dialog box. New picking also takes advantage of OpenMP technology.

User Interface - Dockable Panes

Mesh Control Explorer - New for 2021.1!
- Added Mesh Control Explorer to perform a number of different tasks, including specification of options for mesh propagation, visualization of slaved surfaces for solid meshing and/or mesh approaches on surfaces, and determining if curves are paired by a mesh approach and/or can be automatically paired based on proximity when mesh sizing.
Meshing Toolbox - Overall
- Added icon to open the Mesh Control Explorer dockable pane from within the Meshing Toolbox.
Meshing Toolbox - Mesh Sizing tool

When clicked, the Property Extensions dialog box is displayed, which allows specification of solver-specific items for the current property type. The options available change from property type-to-property type. The “Filter” icon button can be used to limit the tabs which are displayed in the Property Extensions dialog box.
Loads and Boundary Conditions
- Added Equation Coord Sys drop-down to Create Loads dialog box for Model, Load, Nodal; Model, Load, Nodal on Face; Model, Load, Elemental; and Model, Load, Elemental on Face command. The Equation Coord Sys drop-down can be used to specify the coordinate system in which equations are evaluated when defining nodal or elemental loads when Method is set to Variable. By default, this option is set to the active coordinate system in the model, not to match the Definition Coord Sys.
Meshing
- Added a Size Propagation section to the dialog box for the Mesh, Mesh Control, Size on Curve; Mesh, Mesh Control, Size on Surface; and Mesh, Mesh Control, Size on Solid commands. In each command, there is Propagate Sizing option and an icon button which accesses the Mesh Sizing Propagation Options dialog box. The Propagate Sizing option can also be enabled and the other options specified via the Mesh Control Explorer dockable pane, which was added for 2021.1.
- Added Detect Surface Poles option to “Mapped” approaches in the Surface Mesh Approach dialog box. When enabled, the location of “surface poles” will be detected and the selected points may be reordered to create a higher-quality mesh. When disabled, the points are always used as entered.
Listing
- Added Evaluate Group to insure Entity Selection is valid option to List, Groups command. This option is on by default, but only used when the List Entities in Group option is enabled. Simply performs the Group, Operations, Evaluate command on all selected groups before listing the entities in each group.
Output and Post-Processing
- Added Linear and Parabolic Types option to Contour Options dialog box, which controls if averaging of results occurs across boundaries between linear and parabolic solid elements.
Tools
- Added Interference Factor/Proximity Factor option to the Tools, Check, Mesh Interference command. In addition, consolidated the user interface to use a single dialog box instead of a series of questions. When Interference Factor is selected in the Checking Options section, an element has to overlap at least one other element by more than the specified value for the elements to be considered interfering. When Proximity Factor is selected, it acts in an opposite manner to Interference Factor, meaning if a gap smaller than the specified value exists between and element and any other element, those elements are considered interfering.

Preferences

Graphics
- Added New Picking to Graphics Options section. When enabled, which is the default, New Picking uses new picking introduced in version 2021.1 which takes advantage of “Open MP” to improve performance when selecting a large number of entities from the graphics window, especially when using area picking (Box, Circle, Polygon, or Freehand) and/or Front Pick. Unless there is a problem picking entities, New Picking should remain enabled. Fast Picking uses older picking methods, but for the time being should also remain enabled. Eventually, New Picking will become the only available option and these preferences will be removed.
- Updated OpenMP in the Advanced/Debug Options section.to be enabled by default. In addition, now set a default value of “4” for Number of Threads. This functionality has been implemented to improve performance for a limited number of commands and operations including: New Picking; View, Advanced Post, Dynamic IsoSurface; View, Advanced Post, Dynamic Cutting Plane; and placing a contour on certain types of entities. Note: If any issues are encountered when using these options, please disable this option, then contact Customer Support to describe the issue.
Interfaces
- Added Enable Analysis Filtering option and Select Analysis Filters icon button, which accesses the Select Solvers to Filter dialog box. When enabled, this option is used in conjunction with the solvers selected using the Select Analysis Filters icon button to limit solver-specific options found in various locations throughout FEMAP, including dialog boxes and dockable panes. Solvers which can be filtered are MSC Nastran, Autodesk Nastran, LS-DYNA, ABAQUS, ANSYS, SINDA, and MARC. For Simcenter Nastran, certain analysis types can be filtered, including Linear (Contact options including glued contact for most solution sequences), Multistep Structural (SOL 401), Multistep Kinematic (SOL 402), Advanced Nonlinear (SOL 601), and/or Explicit (SOL 701).

Simcenter Femap software is a standalone finite element modeling (FEM) pre- and postprocessor for engineering simulation and analysis. The software is computer-aided design (CAD) independent and can import geometry from all major CAD platforms. It supports most CAD data formats. Simcenter Femap also works in combination with a wide variety of FEA solvers, including Simcenter Nastran® software.

Simcenter Femap, which is part of the Xcelerator portfolio, the comprehensive and integrated portfolio of software and services from Siemens Digital Industries Software, is now being released on a biannual schedule in the spring and the fall, which began with version 2019.1 and continues with version 2021.1. The software is now referred to as Simcenter Femap to reflect that it is a part of the Simcenter portfolio of Siemens computer-aided engineering (CAE) products. For the same reason, NX Nastran software is now Simcenter Nastran software.

The latest release provides a variety of enhancements that will improve your productivity across the simulation workflow. A large amount of functionality added to 2021.1 focuses on facilitating mesh creation and modification. First, matching mesh sizes and determining mesh propagation between disconnected geometric entities can be specified based on the proximity of edge curves to one another. To determine where these mesh propagation options will be enforced, tools were created in the new mesh control explorer pane to provide visual feedback for edge curves, which are fully paired, partially paired or unpaired, along with other tools to visualize which surfaces are paired for solid meshing or have a surface mesh approach assigned. In addition, multiple tools in the meshing toolbox can be used to update an existing hex mesh. Another area of expanded capabilities is support for MSC Nastran SOL 400. From a modeling standpoint, items have been added to specify property extensions, nonlinear materials and contact options designed for use with SOL 400. At the same time, a new analysis type may be selected that offers user interface (UI) elements to define critical and useful solver parameters for SOL 400. Finally, updates have also been implemented for Simcenter Nastran and Abaqus.
