Dear Akshay,

Please have a look at the previous discussion on ResearchGate.(below Link)

https://www.researchgate.net/post/How_can_I_run_my_APDL_macro_from_matlab_m_file

Also go through the Matlab Answer given in these links as they reported the solution using different version of Matlab.

Hope this will help.

Thanks both of you 🙂.

I have solved the problem and It was not the problem of macro code.

when running system commands, the stack size is limited to 512k through an environment variable called KMP_STACKSIZE. It is possible to verify the existence and value of this environment variable by issuing the following command listing all the variables (in Windows):

>>System('SET')

(produces a list of all environment variables currently set...)

For ANSYS to be able to run, you need to increase the stack size before calling the ANSYS executable. You can do this by wrapping the ANSYS call in a batch script or you can do the following:

>>System('SET KMP_STACKSIZE=2048k & "C:\path_to_ansys\ansys[version].exe" [input arguments..]')

Check this out, might be helpful.
