Linux: Mechanical launch issue.

[harikrushna171]

When I try to launch using a specific path and "launch_mechanical," I don't get any errors. However, when I launch mech.App, it throws an error. How do I set up the environment in Linux?

Could you please specify the exact command I should use? I'm new to Linux, and my installation path is
"/XXXXXX/v252/aisol/.workbench". Thank you in advance.

export AWP_ROOT252="/XXX/ansys2025r2/ansys_inc/v252", I already tried this one.

`from ansys.mechanical.core import launch_mechanical
import ansys.mechanical.core as mech

exec_loc = "/XXXXXX/v252/aisol/.workbench"
mechanical = launch_mechanical(exec_file=exec_loc)

app = mech.App(version=252)
print(app)`

@harikrushna171 Thanks for opening discussion.

from ansys.mechanical.core import launch_mechanical

exec_loc = "/usr/ansys_inc/v252/aisol/.workbench"
mechanical = launch_mechanical(exec_file=exec_loc)

Once you mentioned exec_file location, you dont have to input version number again.

@dipinknair ,

Thank you for reply,

I want to use only below method
"app = mech.App(version=252)
print(app)"

It is throwing error. Due to not finding out environment variable inside Linux system.
I already tried "export AWP_ROOT252="/XXX/ansys2025r2/ansys_inc/v252".

In Linux if you are using PyMechanical Embedding , you need to use mechanical-env command before python like
mechanical-env python test.py or start python shell by mechanical-env python.

PyMechanical normally look for Ansys installation folder in default locations. In your case its different,
There are multiple ways to workaround for this issue.

1. You can save the path like this first
   save-ansys-path –name mechanical /XXX/ansys2025r2/ansys_inc/v252 then use mechanical-env python test.py to run your file.
2. export AWP_ROOT252="/XXX/ansys2025r2/ansys_inc/v252 this then use mechanical-env python
3. use it with mechanical-env command itself, eg: mechanical-env -p /XXX/ansys2025r2/ansys_inc/v252 python

Please try above and let me know.

@dipinknair,

Thank you for prompt response.

1. mechanical-env python Test_Mech.py (before i run this command, work without error "AWP_ROOT252="/XXX/ansys2025r2/ansys_inc/v252".
2. mechanical-env -p XXX/ansys2025r2/ansys_inc/v252 python Test_Mech.py

In both cases, I found below error.
Error: XXX/bin/mechanical-env: line 213: python: command not found.

I used this command, and it fetch ANSYS mechanical, but it is just help: ansys-mechanical --help

@harikrushna171 Can you please check if you are using latest PyMechanical version? Could you please try runningfind-mechanical and see if pymechanical is able to get install location. Please use save-ansys-path --name mechanical /XXX/ansys2025r2/ansys_inc/v252/aisol/.workbench so that installed location is saved. Then use mechanical-env python Test_Mech.py to run the script.

Also could you please info on error message ?
