HyperWorks introduces hundreds of new features, helping you to develop better products in a shorter time.The Altair HyperWorks product team is pleased to announce the availability of HyperWorks Solvers 2019.2. Combined with design optimization technology and multi-physics capabilities HyperWorks, this solver technology enables users to drive the product-development process and make reliable decisions based on high-quality results. Altair HyperWorks开发团队已发布HyperWorks Solvers 2019的更新，该更新是用于结构，流体动力学和系统仿真的有限元和多体动力学求解器的集合。 Altair HyperWorks Solvers 2019.2.4发行说明 Altair MotionSolve 2019.2.4发行说明 OML格式的
新功能
A，B，C和D状态矩阵
MotionSolve可以创建OpenMatrix语言（OML）格式的状态空间矩阵。这些矩阵可以直接加载到Compose and Activate中进行进一步分析。可以使用线性参数设置中的属性write_oml = True进行设置。
柔性体的动能和应变能
MotionSolve可以计算使用分量模式综合（CMS）定义的柔性体的动能/应变能和耗散能。
模型能量分布
MotionSolve可以编写具有模态能量分布的HTML文件。HTML文件有助于理解能量如何在不同的模式形状之间分配。可以使用线性参数设置中的属性write_energy_dist = True进行设置。
3D
网格接触3D网格接触算法已通过可选的基于节点的计算接触运动学的方法进行了增强。此功能计算表面网格的节点上的法向力，而不是网格三角形的中心。以节点为中心的接触特征可提高精度，尤其是在由于接触的尖锐边缘而发生较大穿透的情况下。可以使用“联系人：强制”设置中的属性enable_node_mode = True进行设置。
缸内接触
MotionSolve中的接触模型允许使用is_material_inside标志解析地计算另一个圆柱体内的圆柱之间的接触。同样，缸内缸体被支撑用于敞开缸盖缸和缸盖缸（内缸和外缸）。与基于网格的接触计算相比，分析接触公式在速度和准确性方面具有优势。
Linux对MS + EDEM的支持
在2019.1版本中，MotionSolve添加了一项新功能，可与散装材料模拟软件EDEM进行共同仿真。此版本扩展了对Linux操作系统的MotionSolve / EDEM联合仿真的支持。
T> T0处的FMU耦合
MotionSolve与Co-sim功能样机单元（FMU）的协同仿真功能使您可以在T> T0时启动耦合仿真，这意味着MotionSolve从T0（启动时间）到T（耦合时间）不使用FMU来仿真系统。这允许在FMU的动态影响仅在大于T0的时间才有意义的情况下以及FMU在计算上昂贵的情况下提高计算性能。可以使用Control：FMU设置中的属性start_time = <value>进行设置。这对于Model Exchange FMU无效。
增强
了FMU
的运动学分析MotionSolve与FMU的协同仿真功能已扩展到支持运动学分析。
PINSUB和POUTSUB
PINSUB和POUTSUB可用作Python子例程。
FMU的其他调试功能
您可以增加与FMU相关的求解器日志。可以通过设置环境变量MS_FMU_LOGGING_LEVEL =…来完成。
•ALL-记录所有消息。
•警告-每次FMU为其任何功能返回警告状态时，均记录日志消息。
•错误-每次FMU为其任何功能返回错误状态时，记录消息。
•FATAL-每次FMU为其任何功能返回致命错误状态时，均记录日志消息。
此外，您可以指定MotionSolve求解器应打开FMU进行联合仿真的路径。这可以通过设置环境变量MS_FMU_UNPACK_DIR ='<PATH>'来完成，其中<PATH>描述文件夹路径。
符合性检查
已实施了改进的合规性检查，以使与FMU的协同仿真更加可靠。在此，将根据FMI标准检查FMU的有效性，并在FMU不符合该标准的情况下报告警告/错误。
已解决的问题
•对于某些型号，本征模式未在HyperView中正确显示。
•轮胎模型的线性分析有时会导致软件崩溃。
•顶部和底部气缸盖混合在一起。
•解决了模拟完成后，无法删除FMU临时文件夹的问题。
•重新加载后，带有COUXX2的模型的结果是不连续的。
•如果在OptiStruct中运行CMS时使用了非默认单位，则不能正确缩放MotionView生成的阻尼比。
•柔性主体上的分布载荷有两个分量：刚体分量倾向于加速作用于其上的柔性体，而模态分量倾向于使作用于其上的柔性体变形。 。当使用非默认单位时，由Force_FlexModal创建的分布力无法在刚体部件上正确缩放。
•即使您试图将求解器安装在另一个目录或驱动器中，Linux安装程序也会返回有关根目录缺少磁盘空间的错误消息。
•在某些情况下，如果内部和外部气缸之间的穿透力过大，则内部气缸会在气缸内部-气缸接触中被“击去”。
•在MotionSolve中未正确解决某些基于模型交换的功能模型单元。
•保存和加载命令后，与运动标记B1 / B2 / B3对应的内部状态未正确初始化，从而导致运动状态与保存到XML文件中的相应AX / AY / AZ值之间发生偏移。重新加载后，这导致结果有些不连续。
•由MotionView生成的MotionSolve FMU未在Linux上的“激活”中运行。
•MotionSolve子例程生成器无法在Linux平台上执行。Altair Radios 2019.2.3发行说明已解决的问题
施加条件/载荷工况

New Features
Contact interfaces
A new contact gap option Igap= 4 has been added to the contact interface /INTER/TYPE19 whichenables variable gap for the node to surface contact and constant contact gap, Gapmin, for theedge to edge contact. For self-contact, if element size is less than the gap value, then slavenodes are deactivated for nearby master segments. This is the same as using /INTER/TYPE7,Irem_gap= 2.
Animation output
The plastic work of material LAW12, LAW15, and LAW25 are displayed in /ANIM/ELEM/WPLA and /H3D/ELEM/WPLA output, and are no longer in the plastic strain (EPSP) for those material laws.A new option /H3D/NODA/SKID_LINE displays when the draw bead contact (/INTER/TYPE8) occurson the slave side and when it is sliding.A new user input value is available in FLD failure models (/FAIL/FLD) which defines the marginaldefinition zone display in /ANIM/SHELL/FLDZ and /H3D/SHELL/FLDZ.

/FAIL/JOHNSON + XFEM
Memory allocation issue that caused the Engine to fail for models with XFEM in the failure card.
/FAIL/TAB1
The instability strain table (table2_ID) was not being taken into account correctly, and only thevalue for no triaxiality was used.
/INITRUSS/FULL
Input format caused the Starter to fail.
/SUBDOMAIN
Numerical issue for multi-domains (/SUBDOMAIN) and contact interface /INTER/TYPE19 thatcaused the Starter to fail, due to complications with memory allocation.Compilation issue for Open MPI (ompi) version that caused corrupt executables.
/NEGVOL/STOP
A message relative to the FVMBAG was being printed at the same time as a negative volume errormessage in the Engine output file.
/MAT/LAW57 (BARLAT3)
Numerical issue with single Precision version with usage for Barlat material (/MAT/LAW57) andpressure unit defined as "Pa".
/MAT/LAW75 (POROUS)

/LINE
Numerical issue with the /LINE option and domain decomposition in the Starter.
/LOAD/PBLAST
Numerical issue in the Starter when both /LOAD/PBLAST and /INTER/TYPE17 were set in a specificmodel. The Starter failed with a memory allocation error.
/MONVOL/FVMBAG1
Numerical instability in the volume computation for a specific airbag meshed with pyramid andtetrahedron elements. The model failed during the first cycle.Starter initialization correction for a finite volume mesh created with pyramid and tetrahedronelements.Radioss Starter was taking too much time to create the restart files.
/PROP/TYPE9(SH_ORTH)
With Ishell=24, membrane damping (Dm) was not set to the correct value for triangle shellelements (/SH3N) and material law /MAT/LAW19. The value was Dm=0.015, instead of Dm=0.25.

New Features
User Experience
- Real-time assistant unit cell calculations are now automatically calculated and guide meshinput parameters. In addition, real-time assistant unit cell calculations have been verified foraccuracy to the actual exported unit cell.
- Auto selection of Step 1: Unit Cell model mesh algorithm (direct or adaptive) including autocalculation of mesh element size based on unit cell model selection.
- Auto populate Laminate definition default layers for general laminates (orientation = 0,thickness = 1.0) and injection molding laminates (orientation = 0, thickness = 1, fiberorientation tensor = {0.9, 0.1, 0.0, 0.0, 0.0, 0.0.}).
- Added Step 3: Nonlinear Material Characterization summary plot which plots all simulationson one chart as a summary in addition to the individual plots for each simulation.
- Changed Step 3: Nonlinear Material Characterization simulation data from “strain rate” to“test time” which is more consistent with standard macro solvers (that is OptiStruct, Abaqus,and so on) that defines default time for implicit solutions. In addition, default “test time” isset to 1 sec, which is the standard default for macro solvers.
Constituent Material Database
- The Constituent Material Database has been enhanced to include separately continuousmaterial product forms and injection molding material product forms. The proper constituentmaterial (continuous or injection molding) should be selected based on the product formbeing simulated.
- Added Tow material class and corresponding Aramid/Carbon/Glass material subclass to theconstituent material database which enables the constituent material database to be used forwoven materials.
Step 1: Unit Cell Definition
- Support for external unit cells with quadratic elements from OptiStruct (*.fem) and Abaqus(*.inp).
- Added both geometric and manufacturing parametric input for Fibrous > Discontinuous Fiberparametric unit cells.
Resolved Issues
- Added default license file location checkout for EDU package/install.
- Fixed incorrect macro strain calculations with Step 4: Material Nonlinear Characterization dogbonesimulation models.
- Simulation models for injection molding with fiber orientation tensor results no longer requireelement IDs to start at ID=1. Element IDs can now be numbered starting at any number and donot have to be continuously numbered. As such, the mdsFiberOri.dat file now has the headerinput *Max_ElementID instead of *Total number of elements.
- Simulation models for injection molding with fiber orientation tensor results no longer require themodel to be built completely within the global X-Y plane. Simulation models for injection moldingwith fiber orientation tensor results can now be built in ANY 3D XYZ coordinate system, and localelement material orientations are automatically calculated from the local element fiber orientationtensor at every element. Prior versions required the model to be built completely within the globalXY plane (that is Fiber Orientation Tensor results A33 ~ 0.0). With this change, v2019.2 completelysupports A33 >> 0.0.
- The performance of simulation models for injection molding with fiber orientation tensor resultswith explicit solvers (that is, Radioss, Abaqus-explicit, LS-Dyna, and so on) has been significantlyimproved.

Modeling Simulation: Supported Features
Injection molding is one of the most common processes used for the production of polymer parts. Thisis a cyclic process and often used with thermoplastic polymers. A polymer in the form of pellets is mixedwith other additives, then heated to a melt state, and finally pressurized in a single screw extruder.This pressurized polymer melt is injected into the mold at a high flow rate to fill the mold cavities.These cavities are made in the form of the final part accounting for the shrinkage, and then the mold iscooled and the part is ejected from the mold as soon as it is stable enough for ejection. This is a cyclicprocess and this sequence repeats. Altair Manufacturing Solver is used for simulating the injection molding process.The following features are supported:
