My initial idea is to write a .msh file with the deformed mesh (basically with the new coordinates of the nodes). Then I open this .msh in Gmsh to insert a new crack line. For this, I need to create a surface according to the deformed mesh. However, I really don't know if it is possible to create a surface from the elements 1D or 2D. It would be better if I wrote the .msh with only the boundary elements (elements 1D) due to the computational cost.

We can indeed remiss triangulated surfaces : see tuturial gmsh/tutorial/t12.geo
