Hello,

I am new to GMSH and OpenFoam but have some ground knowledge in both.

I found this example in Github:

https://github.com/openfoamtutorials/airfoil_validation

But when I try to mesh the file main.geo with the following command:

gmsh main.geo -3 -o main.msh

I get continuous errors from gmsh:

Error : Wrong list index (read)

Are you familiar with this example and have solve the problem? I would appreciate your help.

Thank you very much.

Hi,


I downloaded and unzipped the zip archive you referenced, cd'ed to the mesh directory and ran


gmsh -3 main.geo


(no need for -o main.msh as this is the default output mesh filename)


It took about a minute, but produced a nice mesh with 73597 elements and no error messages. This was with Gmsh version 3.0.6 as distributed in the Ubuntu 18.04 package.

Hello, Thanks for your answer...

Finally I did manage to sovle the problem. In my case I had to modify the code in each line after "ce++" was called not to subtract -1. Now I get the mesh and can run the example.

Maybe different versions of gmsh?
