Altair SimSolid 2022.3 has just been released with the latest features to increase the users’ ability to complete upfront simulation during the design process.

The new features are as follows:

  • Linux HPC support
  • Squeak and Rattle
  • ECAD reader
  • Transient thermal-stress
  • Imported thermal
  • Alignment
  • Virtual cable/rod

New features in detail:

  1. Linux HPC support

SimSolid now supports a new platform, Red Hat Enterprise Linux. SimSolid jobs can now be run on high-performance computing clusters with batch mode scripts. All functions available in batch mode are also supported on the Linux platform except for importing any geometry files.

The SimSolid user interface is still not supported on Linux platforms.

  1. Squeak and Rattle

Squeak and rattle functionality allow engineers to rapidly identify and eliminate squeak and rattle in products at an early design stage. It can be accessed by linking to transient analysis. Squeak and rattle issues can be identified by creating sampling points across the assembly and evaluating potential issues. Several responses can also be plotted for more details.


3. ECAD reader (Beta)

SimSolid supports the import of Electronics CAD files, generally called ECAD files. ECAD files with extensions .tgz, .tar, .zip, .pcb, .pcbdoc, .xml and .cvg are currently supported, which allows importing several electronic CAD files, including printed circuit boards.

4. Transient thermal stress

Temperatures from the transient thermal analysis can now be used to analyze thermal stresses and deformations. The time steps can be defined manually or imported from a *.csv file.

5. Imported thermal

Temperatures can be imported from a .csv file to map them across the assembly. Temperature import from multiple time steps is also supported. The imported temperatures can then be coupled with structural analysis to perform thermal stress analysis.

6. Alignment

Alignment functionality allows for aligning contact interfaces and geometry features such as cylinders. It is enabled as a new contact condition and a boundary condition called Align under structural analysis. This functionality also allows for resolving any interference between parts.

7. Virtual cable/rod

A new virtual connector called Cable/Rod is now supported. The cable allows for stiffness along the rope under tension, while the rod allows for stiffness along the rod for both tension and compression. The stiffness can be manually defined or set as rigid. Preloading the Cable/Rod is also supported via a boundary condition under structural analysis.

8. Face-to-surface connection

A new workflow for contact-based connections is now available via Face to the surface, allowing connection creation by picking faces in the assembly. Gap and penetration tolerances can be defined, and three levels of resolution are available.
