[Gmsh] Question

[David Colignon]

Hi Cynthia,

your script should first generate a simple text file ( test.par for example ) with the geometrical parameters, like

h1 = 1. ;
w1 = 5. ;
...

then you include this parameters file at the beginning of your main test.geo file:

Include "test.par";
Point(1) = {0, 0, 0, lc};
Point(2) = {0, h1, 0, lc};
Point(3) = {w1, 0, 0, lc};

and finally your script issue the meshing command:

gmsh test.geo -2

Cheers,

Dave
