launch_mapdl() does not return for me

[srhouyu]

Hello, I have ANSYS Student 2021 R2 and ansys-mapdl-core 0.60.1 installed. When I execute the example script:

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

The function launch_mapdl() never return. I waited for a long time but still get nothing.

When I hit Ctrl+C to interrupt the script, I get the following message:

Traceback (most recent call last):
  File "d:\Documents\Visual Studio Code\test.py", line 4, in <module>
    mapdl = launch_mapdl()
  File "C:\Users\ssss\Anaconda3\lib\site-packages\ansys\mapdl\core\launcher.py", line 1160, in launch_mapdl
    mapdl = MapdlGrpc(
  File "C:\Users\ssss\Anaconda3\lib\site-packages\ansys\mapdl\core\mapdl_grpc.py", line 261, in __init__   
    connected = self._connect(
  File "C:\Users\ssss\Anaconda3\lib\site-packages\ansys\mapdl\core\mapdl_grpc.py", line 367, in _connect   
    time.sleep(0.01)
KeyboardInterrupt

The first time when I launched the script, I saw the following message:

Cached ANSYS executable not found
Enter location of ANSYS executable:

So I entered C:\Program Files\ANSYS Inc\ANSYS Student\v212\ansys\bin\winx64\ANSYS.exe. That message never shows again.

At last, I have no problem launching Mechanical APDL and Workbench programs.

Hi @srhouyu try the following, then post what is returned. It will take a few seconds for all the "output" to show up:

from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl(verbose_mapdl=True)

Because of:

Cached ANSYS executable not found
Enter location of ANSYS executable:

I believe you have the wrong executable path in the config.txt file. I am quite convinced because of the installation directory C:\Program Files\ANSYS Inc\ANSYS Student\v212... which is quite unsual.

The file config.txt is located in the repository setting directory.
You can obtain this directory in python using:

>>> import appdirs
>>> appdirs.user_data_dir("ansys-mapdl-core")
'C:\\Users\\USER\\AppData\\Local\\ansys-mapdl-core\\ansys-mapdl-core'

You can delete the file if you wish, or just change the path to the right executable.
