[Gmsh] How to use the plugin crack from the command line

[Rosicley Júnio Rodrigues Rosa]

Hello,

I'm a Master student and I use Gmsh to solve fracture mechanic problems.
>From the interactive mode, I have used the plugin crack to generate a crack
in a surface, but I need to use this plugin from the command line. Is it
possible?

I usually use the script bellow:
     gmsh -2 -clscale 1.0 temp.geo -o temp.msh -algo auto -order 3

I tried to add the following lines to the temp.geo file, but it didn't work.
     Plugin(Crack).Dimension = 1;
     Plugin(Crack).PhysicalGroup = 11;
     Plugin(Crack).Run;

What can I do to solve this problem?

Thank you for your help.

Best regards,
Rosicley
