Altair AcuSolve 2019 Release Notes
Highlights AcuSolve v2019 brings a new radiation model, two new functions to improve user workflow and new HyperMesh based tutorials. In addition, Parasolid geometry compatibility between AcuConsole and other Altair tools has been improved. • Discrete ordinate radiation model: Provides means to simulate radiation through participating media while accounting for directional effects. • Automatic wall treatment: Streamlines the process of general model setup. • Thermal shell command: Improves the process of defining thermal shell element sets. • Geometry compatibility: Parasolid output from Inspire and HyperMesh (minimum version 21.0) readable by AcuConsole.
New Features Discrete ordinate radiation model While the previously released P1 radiation model reduces the radiative transfer equation to a single partial differential equation, the discrete ordinate model computes radiation for a given finite number of ordinate directions, selectable by you. This model is fully coupled with the flow solver and allows for zero absorptivity of participating media. Automatic wall treatment Automatic wall treatment, first released as a new type (= auto_wall) under SIMPLE_BOUNDARY_CONDITION with v2018, greatly simplifies the model setup. This feature processes the model and automatically handles the specification of internal and external wall boundaries, moving and stationary surfaces and interface surfaces. Thermal shell command Previously a manual function, with v2019 you now have access to the THERMAL_SHELL command from within the input deck. With this command the same flexibility is available to create shell elements of varying layers and composition without the manual selection on the model. In addition, because thermal shells are created at runtime, a model is always available in its preshell state. AcuShapesConvert script This new script is offered to facilitate the visualization of previously created .xsp, .ysp, .zsp or .xyzsp files, used with AcuSolve’s integrated optimization feature. The file names are given as input and a shape file of the TSHAPE format can be written out and imported into HyperMesh for visualization. Design variable values can optionally be applied to the shapes to view a particular state of the shape definition. Tutorial additions Three new tutorials have been added for Dispersed Multiphase, Humidity and P1 Radiation. All three tutorials are HyperMesh based.
HyperMesh based tutorial conversions Fifteen tutorials, previously offered only via the AcuConsole interface, are now offered based on the HyperMesh workflow. • ACU1000: HyperWorks UI Introduction • ACU2000: Mixing Elbow Steady • ACU3100: Mixing Elbow Heat Transfer • ACU3101: Mixing Elbow Transient • ACU3200: Greenhouse Radiation • ACU3203: P1 Radiation • ACU3300: Heat Exchanger • ACU4000: Dam Break • ACU4001: Filling Tank • ACU4002: Sloshing Tank • ACU4100: Dispersed Multiphase • ACU4200: Humidity Modeling • ACU5000: Blower Steady • ACU5100: Fan Component • ACU7001: Shape Optimization
Enhancements Improvements to level set multiphase Immiscible multiphase simulation results provide a sharper interface definition through the levelset_bfecc option. Improvements over the earlier levelset option include: improved handling of high aspect ratio elements, more accurate interaction with wall surfaces, and maintaining high accuracy at higher CFL numbers.
Known Issues The following known issues will be addressed in a future release as we continuously improve performance of the software: • New features added to the AcuSolve user profile are not currently supported by the .inp reader. You should not import input decks written from AcuConsole or from HyperMesh 2019.
Resolved Issues • Parasolid v21.0 or later files written from Inspire can now be read into AcuConsole. • File format for .xyzsp files written from HyperMesh corrected. • Corrected an issue with mass flux inlet specification for multiphase simulations. • Resolved an issue with running AcuSolve from a shared, remote disk installation. • Previous limit of 512 SURFACE_OUTPUT commands has been removed; you can now specify as many as desired. • Support for amsmpi has been discontinued.
Altair nanoFluidX 2019 Release Notes
nanoFluidX is a software to simulate single- and multi-phase flows based on the Lagrangian Particle Method "Smoothed Particle Hydrodynamics" (SPH) and is developed and maintained by Altair Engineering. The purpose of this code is to simulate complex flows that are difficult or infeasible to handle using classical CFD approaches such as Finite Volume Methods. The main advantages of SPH are the conservation of mass and momentum (linear and angular) in the absence of physical dissipation e.g. due to viscous shear effects and the exact advection of the particles. As a consequence, SPH is very powerful in dealing with free-surface flows as well as multi-phase flows with complex physical phenomena such as surface-tension or interfacial transport processes.
Highlights • SPH weakly compressible code. • Unique numerical solutions bringing unprecedented accuracy among industrial SPH codes. • Free-surface and high-deformation fluid flows. • Meshless approach, leading to simplified pre-processing. • Multi-phase flows. • Aeration-viscosity models. • Temperature equation and viscosity-temperature dependence models. • Surface tension models. • Adhesion models for fluid-solid contacts. • Defined motion of solid bodies. • Passive rigid body motion (as in fluid-rigid body momentum exchange). • Created and optimized for use on clusters of Graphical Processing Units (GPUs), making it extremely fast.
New Features Optional use of low-dissipation 1st order Riemann solver Greatly improves accuracy and the representation of the pressure field.
Note: This feature is considered experimental when used in multiphase mode.
Moving Least Squares correction for gradients Further improves accuracy. New optional particle position correction scheme APD (Artificial Particle Displacement) nanoFluidXcompanion (nFXc) A post-processing tool for converting SPH particle data to a mesh-based data for easier treatment and visualization in ParaView.
Aeration-viscosity models Account for the change of viscosity as a function of the air entrapment. Has beneficial influence on the torque prediction, especially in cases where torque comes mostly from shear stress. Primitive adhesion model Adhesion models which depend on an adjustable numerical parameter. Though it improves the capability of capturing film formations, the model has to be tuned to the experimental results. Monitoring probes Observe the flow at a specified location for any physical property. Circular inlets Improved motions Improved impose regions (momentum sources) Fluid Contact Time (FCT) Show contact time history between solid elements and a chosen fluid, which is useful for qualitative analysis of oil supply and lubrication. Operational modes Allow for a “single command setup”, depending on what is the required level of speed/accuracy ratio.
Enhancements Supported Platforms All Unix-based OS with GCC newer than 4.4.7 and GLIBC 2.12 (RHEL 6.x and 7.x and compatible Scientific Linux, CentOS, Ubuntu 14.04 and 16.04, OpenSUSE 13.2, and so on.) NVIDIA CUDA 8.0 and OpenMPI 2.1.5 – shipped with the binary.
Current Limitations • Surface tension coefficient for single phase flows requires tuning, as no universal single phase surface tension model exists. • Adhesion coefficient needs to be calibrated against experimental results or visually estimated. • Large negative pressures cannot be accurately handled by the current weakly compressible formulation without total particle volume preservation.
Resolved Issues • Improved robustness of the restart (disappearing phases at rank borders are addressed). • Planetary motion – rotation around y axis is now fixed. • Fixed particle overlapping check, so that it shows consistent numbers between phases.
Altair ultraFluidX 2019 Release Notes
New Features Mesh import You can now reuse an existing discretization from a previous ultraFluidX simulation to skip the meshing step and save computational time. Increased performance Simulation performance has increased due to internal code restructuring and a new data structure for the wall modeling.
Enhancements Velocity information on rotating and moving surfaces Velocity information is now displayed on rotating and moving no-slip walls in the surface data to be able to visualize the correct setting of rotating and moving boundary conditions. Sectional force coefficients in y- and z-direction Force coefficient output has been enhanced with full sectional coefficients in y- and z-direction, according to a user-specified number of sections. This supersedes the previously available z-split of the force coefficient output. Averaged mass flow included in the summary Averaged mass flow files are now created, and report the averaged mass flow per porous medium in the simulation summary file. Improved surface mapping at the transition of refinement levels The method used for evaluating macroscopic data at the transition of refinement levels for the surface mapping has been improved. This yields a better representation of surface data in areas where the grid is refined near the surface of the obstacle. Possibility to specify start iterations for all output categories You can now specify when to start the output for each of the available output categories. This feature can be used to generate high-frequency output for a specific part of the domain or the full volume data once the initial transient phase is completed. Selection of output variables You can now select the field variables that should be included in the output. Monochromatic acoustic point source A monochromatic acoustic wave with prescribed amplitude and frequency can now be injected into the simulation. Probe output in sub-iterations Probe output now also is enabled in sub-time steps instead of the coarsest iteration only. This can be used to extract high-resolution results for acoustic analyses. In the same breadth, buffers in probe output and drag/lift files now are flushed in every iteration.
