Dear all,

I would like to create a mesh using GMSH software. Unfortunely, the compilation procedure can not finish due to the errors with the report "2 boundary nodes are considered once".

Could anyone please help me to solve the problem?

Thank you so much in advance

Sincerely yours,
Xuan Nam Do
