Dear Prof. Geuzaine, Mille grand merci.
The question is I only need the nodes on the on the tagged Physical Surface surface. For instance: in the msh abaqus.inp with "Save groups of nodes" option: my tagged surface is: *ELSET,ELSET=PeriodicSurfacePS 589727, ...... where ******* E L E M E N T S ************* *ELEMENT, type=CPS6, ELSET=Surface7 589727, 1150, 13, 18137, 1170, 18413, 18414 are then the nodes of the SURFACE ELEMENT 589727 but what I am missing then is : this surface element is not one of the faces of a 3D tetrahedra element as I cannot find an element 589727 in the Volume : *ELEMENT, type=C3D10, ELSET=Volume1 If I use the nodes from the line: 1150, 13, 18137, 1170, 18413, 18414 for the surface element 589727, I am set?
