[Gmsh] gmsh and python

[Eiser, Sebastian]

Elisabetta,
I'm also curious on the python interface and heard about it, but have never used it. From what you write though, it may be sufficient to do this in a python script:

#!/usr/bin/python
from subprocess import call
# you script that writes "input.geo"
# ... 
# after writing the geo file, call gmsh
call(["gmsh", "-2", "-order 2", "input.geo", "-o", "out.msh"])

Alternatively, you can put everything into a (e.g.) bash script (if you use Linux)

#!/bin/bash
python createGeometry.py # writes "input.geo"
gmsh -2 input.geo -o out.msh 

hope this helps

Subject: [Gmsh] gmsh and python

Dear gmsh developper,
I would use gmsh to implement my project. I would to use my code written in Python to run gmsh to build the geometry and the mesh of my problem domain and after save results.

I see that is possible to interface gmsh and python script. Currently I written a phyton script that writes the .geo file to build my geometry. 
I would like to known how I can open gmsh and run my gmsh-files in gmsh using python. Where I can find a tutorial with commands to interface python and gmsh?

Thank you very much

Elisabetta Sieni
