 I want to conduct explicit dynamic due to the large deformation and contact. However, I need to use the apdl in HPC. In workbench, I know

there is explicit dynamic module (unfortunately, not available on HPC). Therefore, I am wondering whether I can conduct explicit dynamic

analysis with APDL. Thanks,

 

PS. I know in workbench, static structures analysis or transient structure analysis can write input file, which can be used in APDL directly. I am wondering whether explicit dynamics analysis have this option.

Explicit Dynamics uses the AUTODYN solver not the MAPDL solver. You cannot use APDL commands with Explicit Dynamics.

You would have to contact your system admin to have it set up. What university are you from?

Hello SandeepMedikonda

    Thanks for your reply. I am from Mcgill and my lab buy ansys license from CMC. You mean I need to add the autodyn to apdl?

Thanks for your response. Actually, My license grant access for AUTODYN and Explicit Dynamics and I can access explicit dynamic through workbench. However, currently my problem is that I cannot open workbench graphic user interface on a cluster and I need to run it in batch mode. I wonder if it is possible or explicit dynamic can be run solely through workbench

Explicit Dynamics should be available to you on Linux. I've just tested this. You would have to reach out to your Admin or Ansys Support Coordinator (ASC) to have this configured or ask them to reach out to us so that we can escalate and help to have graphics or RSM setup.

There is a bit of a setup process involved for using Explicit Dynamics on HPC.

These links should've all the details you would need to setup Explicit Dynamics Simulations on Linux. Note that Platform MPI is a pre-requisite on Linux.
