This python process is not related with the gid.exe process (it is not an embedded Python)

It can be used for example to run a GiD problemtype Python-based solver, without need to install installing an extra Python, the one of GiD could be usedby using GiD’s python, and its relative location is known a priori known.

If this process is killed the gid process is not affected, and they don’t share any memory.

It is possible to import the tohil module in this Python interpreter to call Tcl commands, but this will create a new Tcl interpreter with the standard commands, it is not possible to use here Tcl commands. Thus GiD commands like tohil.call( 'GiD_Info', 'mesh', 'nodes', '-array') or tcl.GiD_Info( 'mesh', 'nodes', '-array') can not be called.

Example:
