pre-processing

Post by kamyarsa » Thu May 26, 2022 9:29 am

Hi,

Is there any software for pre-processing (to build the geometry of the model, and then import them to Python to perform the analysis)? I guess there are STKO and GiD, but they only output the tcl scripts, right?

Thank you for your help!

Hi Kamyar,

The main purpose of pre-processing is to have model Nodes and Elements information (i.e. Coordinates and ID's).
You can use any software that can generate meshes and give above data's to you, for using it in both tcl and python interpreter.

I'm Currently using GiD (Also GiD+OpenSees problem type is helpful), but you can also use gmsh as a pre-processor.

Thank you for your response.

So, Gmsh can help me in outputting the coordinate script? what is the script language? Is it possible to change it to a python script to feed that to OpenSEESPY?

Gmsh itself has a Python package. And yes, you can extract all node coordinates and elements nodal tags after meshing for use in both tcl and python interpreters of OpenSees.
