Thank you for your annotation.

Hello, I create a simple box in freecad. The .inp of this file is the following one: DEFAULT .INP file ** written by FreeCAD inp file writer for CalculiX,Abaqus meshes ** highest dimension mesh elements only. ** Nodes *Node, NSET=Nall 1, 0, 0, 10 2, 0, 0, 0 3, 0, 30, 10 4, 0, 30, 0 5, 20, 0, 10 6, 2...

FreeCAD supports multiple materials too. You may make you model in FreeCAD directly.

Yes I know, but the final objetive of the project is to manage different custom .inp files from a macro without modifying the structure of the mesh.

SimpleBox.FEMMeshGmsh.Elem0F1 (FEMMeshGmsh) SimpleBox.FEMMeshGmsh.Elem42F1 (FEMMeshGmsh) SimpleBox.FEMMeshGmsh.Elem42F2 (FEMMeshGmsh) SimpleBox.FEMMeshGmsh.Elem39F4 (FEMMeshGmsh) - Elem0F1 means Face 1 of element 0 - Elem42F1 means Face 1 of element 42 - Elem42F2 means Face 2 of element 42 - Elem39...

Hello, Wow! I am interested in this topic. I need practically the same. I create a simple box in freecad. The .inp of this file is the following one: DEFAULT .INP file ** written by FreeCAD inp file writer for CalculiX,Abaqus meshes ** highest dimension mesh elements only. ** Nodes *Node, NSET=Nall ...

BTW: what do you need them for?

I am exploring and editing manually the .inp file for performing different frequency analyses.

I can attach a simple example file.

It is possible to define a material set SOLELY to ONE node? Usually material properties are defined on elements, but in CalculiX there is a special element type for defining mass at node. Look to the manual on the element types and *MASS card http://www.feacluster.com/CalculiX/ccx_2.13/doc/ccx/node...

Hello, I am trying to select a simple element (type C3D10) from Gmsh mesh for changing the material solely to the selected element. Using the mouse, in the Selection View I can click and check the following elements (e.g.) SimpleBox.FEMMeshGmsh.Elem0F1 (FEMMeshGmsh) SimpleBox.FEMMeshGmsh.Elem42F1 (F...

Thank you.

I think this is more a fem related issue than a material related issue. However don't know why you need a singe node as another material... The only way to archive this i thing would be add a point to the model and mark the model as one material and the other part(s) as their own material(s). I thi...
