“Mechanical APDL Batch running with 2 cores requested” Problem

[JordanPeach]

Hello to whoever is reading this.....,

currently, i'm trying to use Python in combination with Ansys 2022 R1 for the first time using all the packages that falls under PyAnsys. This is the program in question......

 from ansys.mapdl.core import launch_mapdl
 mapdl = launch_mapdl()
 print(mapdl) 

However, i'm running into an issue. When I run this program, it shows a new window saying "Mechanical APDL Batch running with 2 cores requested" but in task manager, its listed as "not responding". Furthermore, when I try to click on this new window, i'm met with the following System Errors:

1. "The code execution cannot proceed because AnsMPI.dll was not found. Reinstalling the programme may fix this problem"

2. "The code execution cannot proceed because AnsGPU.dll was not found. Reinstalling the programme may fix this problem"

3. "The code execution cannot proceed because ansScaLAPACK.dll was not found. Reinstalling the programme may fix this problem"

4. "The code execution cannot proceed because libifcoremd.dll was not found. Reinstalling the programme may fix this problem"

I've checked all these aforementioned files and they're all present within the Ansys folder.

It should also be noted that both Python and Ansys are on seperate storage drives on the same laptop due to storage issues. However, when I reinstalled Python onto the same storage drive that stored Ansys, the problem still persisted.

Any help to fix this issue will be greatly appreciated. How do I fix this issue?

Regards, Jordan.

Hi @JordanPeach most of what you describe is normal behavior i.e. a new window is opened and the task manager showing the first ansys.exe process as 'not responding'. The messages about the dll's could be an issue. Some other program may have put a copy of libifcoremd.dll in the Windows system folder which is a different version than what was installed for Ansys (MAPDL). You may want to look in C:\Windows\System32 for that dll and rename it to libifcoremd.dllold. Then start up MAPDL (not via PyMAPDL) in Start -> All Programs -> Ansys 2022 R1 -> Mechanical Product Launcher. On the Product Launcher just click the Run button in the lower left. If there is still a dll issue there will be a pop-open window with a message. If not you can close MAPDL interactive in the upper left under File -> Exit.

I think I may have seen the dll put in other Windows system folder(s)....I'll search my prior service requests and add a message if needed.

Hi @JordanPeach any update on this? Mike

Yes, I have resolved this issue. Thank you for your input.

Initially, I though that there was something wrong but after a more in-depth analysis, it seems everything is now in working order. I guess I had misinterpreted the situation, believing that there was an actual problem with the software when there wasn't in the first place. Tbh, I've never used Ansys APDL before so this is my first time experiencing all this.

P.S: I would mark this discussion as "Answered" but your response wasn't really the solution to the issue as there was no issue to begin with. However, I'm tempted to leave this discussion still up for anyone if the future who makes the same blunder as me....

I've already made the same problem as you, and I want to ask you how you solved it in the first place?Thank you！！！

As @mikerife, that's the normal behaviour. If you do "try to open" that non-responding windows, you might experience issues.

By the way, the ansys.exe process is not responding because it is actually listening to PyMAPDL, so it is not expecting any input from any other source (GUI, text, etc) except its gRPC channel (normally open at the port 50052).
