Hi @vnamdeo, thank you for opening this issue!
I launched PyMAPDL on my local machine with the following parameters:
- OS:
Windows 10 - MAPDL Version:
23.1 - Python version:
3.12.2 - ansys-mapdl-core:
0.68.1
It seems to work fine on my side. Could you add the PyMAPDL report in your issue please? It might help me to understand what's happening.
Here is what I obtained when launching PyMAPDL:
>>> mapdl = launch_mapdl()
>>> print(mapdl)
Product: Ansys Mechanical Enterprise
MAPDL Version: 23.1
ansys.mapdl Version: 0.68.1@clatapie : Please find attached report for the further investigations.
@clatapie Please find attached report using PyMAPDL version 0.68.1,
@clatapie Based on further investigations, it appears that, we are getting errors when we launch mapdl using default options, e.g.
mapdl = launch_mapdl() --> getting errors as reported initially.
However, we able to launch mapdl successfully, if we specify the version, e.g.
mapdl = launch_mapdl(version = 24.1) or mapdl = launch_mapdl(version = 241) --> working as expected.
Hi @vnamdeo
I think there is a problem with either your envvars, or which one of your versions.
Please follow the steps given in https://mapdl.docs.pyansys.com/version/stable/user_guide/troubleshoot.html#debug-in-pymapdl and post here the log file (mylog.log). That file will tell you which command is trying to execute, and then we can try that in a terminal.
Hi @germa89 , Followed steps as mentioned in the Troubleshooting help doc, but, it couldn't save log file. However, please refer to the attached image for the further debug.
When we add version = 24.1, we able to launch PyMAPDL with no errors, please refer to the attached image for reference.
Can you try in a terminal:
"C:\Program Files\ANSYS Inc\v231\ansys\bin\winx64\ansys231.exe" -j file -np 2 -b __tmp__.inp -o __tmp__.out -port 50052 -grpc
and put the output here?
@germa89 Is the default MAPDL version is v231 on launch_mapdl( ) ?
If we execute above line in a terminal, the output is,
"The system cannot find the path specified. "
I realise you are trying to launch MAPDL 231, but you do not have it installed.
Maybe you had it installed and uninstalled it. But the config.txt still has it.
You can check this file by doing in python:
>>> from ansys.tools.path.path import CONFIG_FILE
>>> print(CONFIG_FILE)
/Users/user/Library/Application Support/ansys_tools_path/config.txtto change this, the best is either delete that file, or:
>>> from ansys.tools.path import change_default_mapdl_path, get_mapdl_path
>>> change_default_mapdl_path('C:\Program Files\ANSYS Inc\v231\ansys\bin\winx64\ansys231.exe')
>>> get_mapdl_path()
C:\Program Files\ANSYS Inc\v231\ansys\bin\winx64\ansys231.exe@germa89 In the first place, why launch_mapdl() usage Ansys v231 to launch. What is the default version is ?
whatever is written in the CONFIG_FILE.
This file is created the first time you run PyMAPDL EVER in a PC.
@germa89 Earlier, I am not getting such errors and using PyMAPDL from long time. Recently, I migrated to newer PyMAPDL version and new Python interpreter since then I am observing such issues. Ideally, we should set some default version "latest mapdl version" on version option of launch_mapdl () function to invoke rather grab it from the CONFIG_FILE, which is not ideal approach as you have observed it. Thanks !
You are right. I acknowledge there are some corners to polish. PyMAPDL should probably re-detect MAPDL if the file cannot be found.
I will look into that. I'm keeping this issue open for future fix.
In the meantime, please delete CONFIG.txt file, it should work OK after that.
