[Gmsh] Question

[Cynthia Maxwell]

Hello there,

I am thinking of using your product with my solver.
I would like to define a geometry and iteratively change some  
parameters such as width, height, ellipse center and radii as seen  
below:


You say GMesh can:
"parameterize these geometries. Gmsh's scripting language enables all  
commands and command arguments to depend on previous calculations  
(see 2.1 Expressions, and 3.1 Geometry commands);"

How would I do this? Do you have any examples of parametrically  
modifying a geometry say from a script?

I hope you do, because this would solve my mesh generation problem  
and allow me to focus on the solver.

The sooner the better I know : )

Thank you,
Cynthia
