Hello,

I am running simulation using LS DYNA MPP on linux HPC and getting following error :

Is anything wrong with my batch script?

#!/bin/bash -l

Hello Atish, 

Could you please verify that lsdyna_dp_mpp.e in your ansys folder is a version of ls-dyna compiled form OpenMPI? Or could you download the ls-dyna for OpenMPI from here https://ftp.lstc.com/user/download_page.html (username: user ; password: computer), upload it to your server and try it? 

Could you please check if you have all dynamically linked libraries for lsdyna_dp_mpp.e. Please run this on your cluster: 

ldd  /opt/apps/ansys/2024R1/ansys_inc/v241/ansys/bin/linx64/lsdyna_dp_mpp.e

Please let me know if that helps, 
Thank you,
Alex

Thank you Alex,

See below outcome of ldd command. I think some files seems to be missing.

I also downloaded the following files from the LSTC website. Could you please instruct the procedure to install  following OpenMPI files on linux?

ls-dyna_mpp_d_R15_0_2_x64_centos79_ifort190_sse2_openmpi405.tgz_extractor.sh 

ls-dyna_mpp_d_R15_0_2_x64_centos79_ifort190_sse2_openmpi405_sharelib.tar.gz_extractor.sh

Hello Atish, 

Please unpack the files and upload them to your server. The solver is already executable, so no installation is needed. However, you may need to adjust the file permissions to allow execution.

Thank you,

Alex
