Hello,
i am trying to create a reference point on a node area inside a cylinder.
How can i perform this? On a flat surface, I can do this in CAD using ‘split surface’, for example. Is it also possible to do this in PrePoMax?
Example another FEM software:
Shorten the Z-width to between 31 mm and 47 mm, and the Y-height to between 140 mm and 166 mm.
PrePoMax File here:
Many thanks in advice!
I can’t access it, there’s an error:
Error
The URL doesn’t have the correct format.
But can you share the .pmx file too ?
However, you should partition the surface in CAD software to get such a node set on a uniform surface patch. I can provide some tips on how to do it in FreeCAD if you want.

I am working with inventor but freecad also fine.
Many thanks!
Ok, but this .pmx file doesn’t include CAD geometry, only the mesh. Do you have those parts in STEP too ? Anyway, here’s how it can be done in FreeCAD: https://wiki.freecad.org/FEM_Geometry_Preparation_and_Meshing#Partitioning_faces_of_solids_with_datum_planes
my fault here the STP files:

To create the split surface like this its easy:
The problem is more when the contact area is like this:
It is not possible to select nodes based on the size of the bounding box. The best way is to create a split geometry.
There is also a way to select nodes manually on the mesh by clicking the More button in the Set Selection window and using commands from the FE mesh-based selection. There, you can add or subtract nodes by area selection.
Thanks! I already found a workaround for the Split Face feature in Inventor.
I created a circle in 2D geometry and then used two offsets to split the other faces.
