MSC Dytran 2019


MSC Dytran 2019

MSC Software Corp. has released the latest version of Dytran, its explicit dynamics simulation software. In the latest release, 2019.0, a number of User Defined Services (UDS) have been introduced, along with improvements to the user experience, software performance and simulation robustness.

Dytran is widely used for simulating crash, impact, fluid-structure interaction (FSI), and other short-duration events, as well as for analyzing the nonlinear behaviors that structures undergo during such events. It does so by coupling structural finite element analysis (FEA), material flow and FSI capabilities, allowing simulation across a range of domains.

Looking at the company’s website, the software even allows you to simulate bird strikes on aircraft…which is good news for birds.

New and enhanced features in this release include:

  • User Defined Services (UDS): Dytran now supports UDS.
  • Automated Coupling Surface (ACS):
    • Dytran DMP can now be used when ACS is activated in a model.
    • The ACS coupling surface can now be allowed to “fail.” Once an element of the structure has failed, it will be removed from the calculation and the gap will be considered a hole in the coupling surface.
    • A number of robustness enhancements have been implemented.
  • Cohesive friction:
    • Cohesive friction can now be defined locally on a surface interface.
  • Dytran Explorer:
    • Queuing and scheduling have been added.
    • Processing of UDS services has been added.

And, of course, Dytran 2019.0 is compatible with HPC solutions, and can in some cases, make use of the parallel processing facility for distributed memory systems.
