Hello, I want to post two problems when I install LS-Dyan on Linux system. 

1. Parallel Computing with MPP: I’ve selected the MPP option for parallel computation, but I encountered an error message when trying to run it. Could you help me understand how to properly set it up for parallel computing?

2. When I used this command line to run K file, it give an error. But I can run this K file in LS-Run.

I welcome any feedback here.  Thank you!

Hello Feng,

 

1. Did you install any of the supported MPIs to run MPP? We support MS MPI, Intel MPI, Platform MPI, and Open MPI. Please make sure that any one of this is set up properly.
2. You need to set an environment variable for the license error, with the variable value as your license file name. For more details, follow this: LSDYNA Environment variables

 

Both MS mpi and Intel mpi come in the standard Ansys installation setup. You can find more details in the installation notes.

Regards,

Nanda.

Hi Nanda,

Thank you for your reply. I appreciate your guidance.

However, I did not see the MPI option during the installation process. Could you kindly provide more details on how I can ensure that MPI is installed properly, or if there is a separate installation step for it?

Hello,

Is this a student version? I'm unsure if it supports MPP. Can you please confirm?

Regards,

Nanda

Hi Nanda,

 

Thank you!

 

It is a Ansys research license associated with Northwestern McCormick. We installed the 2024R1 version using the iso files on a Ubuntu 22.04 server. Will MPP work for another version? 

 

Also for the second question about setting up the environment variable to address the license error, we created a LSTC_FILE in the same directory as the LS-DYNA excutable, with two lines: 

 

#LI­CENSE_­TYPE: net­work

 #LI­CENSE_­SERV­ER: 1055@ourservername

 

But Ansys didn't react when I ran LS-DYNA in the terminal. Is there anything wrong with the LSTC_FILE that I should fix?
