PyMechanical: Opening an existing mechdat file while launching PyMechanical

Hello Everyone,

I'm new to PyMechanical and I'm currently trying to launch an existing mechdat file using PyMechanical.

I have tried a few things like:

mechanical = launch_mechanical()
mechanical.open('path/to/file')

None were of success, in this case 'open' is not attribute of mechanical. Printing dir(mechanical) to get the available attributes didn't get me any further. I struggle to find documentation on this matter as most examples deal with importing geometries and building the model from scratch.

I apologize if this is a <?WORD FLAGGED?> question, but I'd greatly appreciate any help.

Thank you!

best regards

Hi @Leonardo9926 thanks for your question! It's a good one. I am not sure myself but it should be straightforward I'd have thought? How to launch an existing mechdat file using PyMechanical. Hopefully someone from @Structures-Scripting-Team could help?

Hi @James Derrick , thank you for your quick response.

I have found a way of doing it. Instead of opening an existing file using launch_mechanical directly, I used the run_python_script(...) command.

So it would look like:

mechanical = launch_mechanical()
script = """
ExtAPI.DataModel.Project.Open("Path\\to\\file")
"""
mechanical.run_python_script(script)

So the entire script string is interpreted as a mechanical scripting command and further functionalities/actions can be achieved by using additional script commands.

Maybe this is not the way it is meant to be done, but so far it's workig for me, so others might use this approach as well.

That's excellent! Glad to hear it worked and thank you for sharing your solution here as well.
