Coincident merged meshes

General Questions

Hello

I have several geom faces (step import) to mesh in order to form one single part (with condensed merged nodes at interface of faces).
NB: I need those distinct faces for applying specific local materials and properties.

I tried to impose nodes distributions on edges, but meshing lead to non-coincident nodes at faces interfaces.
What is the best way to follow ?

My Meshing result:

My mesh nodes distribution / refinement:

What I am supposed to get :

Here is my STEP file (geom faces):

Thanks.

You can create a compound part from these faces. Then (with the default settings) you will get a continuous mesh. And you will still be able to select individual faces for BCs/loads or for section assignments (via elsets).

However, the easiest way in such cases might be to create face partitions in CAD software before exporting to PrePoMax. Even FreeCAD has pretty good tools for that.
