MAPDL server connection terminated when running on linux container #3070

🤓 Before submitting the issue

🔍 Description of the bug

I am importing a cdb (brake aqueal problem in PyMAPDL help doc 1.6 Analysis and solution controls are highlighted: linear non-prestressed modal, partial nonlinear perturbed modal, and full nonlinear perturbed modal.)

Towards the end of the script the connection terminates and we are unable to finish the simulation.

This is running on Ansys Notebook (jupyter backend for execution) and the mapdl product is in a linux container with 8 cores and 64 GB of memory.

File to reproduce, please contact me to get Notebook access if preferred.

🕵️ Steps To Reproduce

See attached file

💻 Which Operating System are you using?

Linux

🐍 Which Python version are you using?

3.9

💾 Which MAPDL version are you using?

2024R1

MapdlExitedError: MAPDL server connection terminated
germa89 commented 1 month ago

Just to make sure... you said the container has allocated 64 GB of ram? and 8 cores?

I have seen issues with MAPDL containers when they run out of memory, in that case the OS kill the MAPDL process very quickly. I would encourage you to increase RAM and cores. If those values are already high (as you mentioned), please set also memory-swap option. Also set a high shm memory limit. If your CPU supports it, you can also disable the out of memory killer using --oom-kill-disable.

Check https://github.com/ansys/pymapdl/blob/9580a45136331a2f5ed00be20eeabb2cf9195b3c/.github/workflows/ci.yml#L613 for some ideas.

You might want to impose some memory limits to MAPDL. This limits should be way lower than the docker container memory specifications. Check: https://www.padtinc.com/2012/02/29/starting-ansys-products-from-the-command-line/

Thanks German.

@prateek-shukla @yingjinsun this issue is from Notebook terminating mapdl on large simulations. Can either of you confirm the ram and cpu set for mapdl and if we can set this option?
