Hello! I’ve spoken to a couple of the developers in person but I figured I’d ask here for a wider reach.

I’m currently using a python script to execute the SPHARM-PDM module in a command line interface (CLI) via python’s `subprocess.run()` function. However, my script never fully completes as the SPHARM process never actually exits upon completion (I have to terminate the script via `ctrl + c` to actually end it). I know I can manually exit my python script using a timeout function, but there’s no way of knowing that all of my meshes (\>100) were generated successfully.

I notice that when I run SPHARM via CLI through a bash shell by itself, the process doesn’t have an exit code to automatically end it after the output is printed, and I have to click enter or `ctrl + c` to get to the next input line/command prompt. I’m guessing this is causing my python script to never complete, as it’s still waiting for the exit code from SPHARM.

Is there a workaround for this, or is this something that can be implemented in a future version of SALT?

Thanks in advance and I appreciate any input!
