Enter the location of an ANSYS executable (ansysXXX)

[manarshhjot]

I am new to PyMAPDL. I am following the ansys course tutorials. However whenever I try to call/import any function I get a message

Cached ANSYS executable not found
You are about to enter manually the path of the ANSYS MAPDL executable (ansysXXX, where XXX is the versionThis file is very likely to contained in path ending in 'vXXX/ansys/bin/ansysXXX', but it is not required.

If you experience problems with the input path you can overwrite the configuration file by typing:
>>> from ansys.mapdl.core.launcher import save_ansys_path
>>> save_ansys_path('/new/path/to/executable/')

I tried by manually adding the address to ANSYS222 and also tried using the suggested commands but nothing fixes the issue.

Hi @manarshhjot,

I recently updated to v222 locally as well and had to just do this. I'm on Linux and MAPDL is installed in the default location at /ansys_inc on my machine, so launching MAPDL for me is just:

$ python
Python 3.9.13 (main, May 23 2022, 21:57:12) 
[GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from ansys.mapdl.core import launch_mapdl
>>> mapdl = launch_mapdl(exec_file='/usr/ansys_inc/v222/ansys/bin/ansys222')
>>> print(mapdl)
Product:             Ansys Mechanical Enterprise
MAPDL Version:       22.2
ansys.mapdl Version: 0.63.0

Since my default MAPDL was set to v22.1 (2022R1) I've updated my default path to the latest version with:

>>> from ansys.mapdl.core.launcher import save_ansys_path
>>> save_ansys_path('/usr/ansys_inc/v222/ansys/bin/ansys222')
'/usr/ansys_inc/v222/ansys/bin/ansys222'
>>> mapdl = launch_mapdl(); print(mapdl)
Product:             Ansys Mechanical Enterprise
MAPDL Version:       22.2
ansys.mapdl Version: 0.63.0

I'm going to update our docs and include an example for save_ansys_path. I'm surprised I didn't find one.

Hello @akaszynski

Thank you for your response.

I am using Windows OS. I had tried to manually provide the path using both the methods but I always run into error.

I presume this got solved?

PR #1332 should help on this.

Hi @manarshhjot

Your path is a bit weird (the ANSYS Student and such). However, could you try to add the .exe ending to your ansys executable path?

[vinothirudayanathan]

To elobrate..

the MAPDL.exe is esisting in my c-drive. where ansys_student has been installed.

in my cmd the " echo %MAPDL% " shows the exact directorywhere the mapdl.exe is installed.

the same has been updated in the path variable both locally and system variable path...

wherees the "ansys_path, ansys_version = find_ansys()" gets out a result
ansys_path -> empty string with single quot ('')
ansys_version -> ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

this is all what I was able to do with my limited knowledge

Hi @vinothirudayanathan "MAPDL" is not a Ansys environment variable. Unless you are starting MAPDL via some custom written dos batch file and created it yourself? Please do the following, in a dos command window enter:

set > c:\envvar.txt

and attach the resulting envvar.txt file here. Mike

Hi @vinothirudayanathan Here are the environment variables that should exist (well, for Ansys...there will be many others):

ANSYS222_DIR=C:\Program Files\ANSYS Inc\v222\ANSYS
AWP_ROOT222=C:\Program Files\ANSYS Inc\v222
ANSYS_SYSDIR=winx64
AWP_LOCALE222=en-us

The Locale may be something different...but based on what you have posted I find it likely that it would be set to en-us.

[vinothirudayanathan]

I'm sorry.
I give up..

[mikerife]

@vinothirudayanathan don't give up - if you are an engineer, or plan to be one, troubleshooting software installation/configuration is a career long task! Alternatively you may want to post your question here at the Ansys Forum. There may be others closer to your time zone that can have a real-time conversation with you on getting this configured properly. https://forum.ansys.com/

from ansys.mapdl import core as pymapdl

new_path = "C:\\Program Files\\ANSYS Inc\\v212\\ANSYS\\bin\\winx64\\ansys222.exe"
pymapdl.change_default_ansys_path(new_path)

This is the right answer which also solve my problem too.
