Splitting surfaces
Make 2D meshes on splitted interface
For 1st solid, create 3D mesh by drag
For 1st solid, use 3D => drag => drag elems
The mesh of 1st solid
For 2nd solid, apply the same method, but for both “2D_1” & “2D_2”
The 2nd mesh
And finally the assembly with coincident mesh on contact interface:
HM model: peca_hexa_hm
