Internal nodes [SOLVED]

Hello,

How can I see the internal nodes?

EDIT: SOLVED

From the mesh or from results mesh?

From the mesh or from results mesh?

Hello Bernd,

Thank you for your fast response. Maybe I dont explain correctly, it was my first post .
When I do a mesh, I can visualize the external nodes (on the surface) and it can be "selected" with the mouse. However, I want to be able to select both surface and internal nodes using the mouse.

I attach a coarse mesh of a simple cilinder to see the results.

Hi,

I found a solution. ShowInner = True option allows to see the internal nodes and meshgrid.

The python API code is the following one:

Code: Select all

FreeCADGui.getDocument("Unnamed").getObject("FEMMeshNetgen").ShowInner = True

thank you.

Ekaitz.

Yep thats it, but only if you have less than 50000 Faces. Above this you need to increase the Parameter "Max Faces Show Inner"

Thank you bernd

Not to forget. If faces are set to be shown the internal of the mesh can only be seen if trancparency is set to somewhat >> 0

The FEM clipping box works with the FEM mesh too. Just the selection of the clipping plane has to be done on a normal part. But this usually exists if there is a FEM mesh.

Thank you, very interesting for selecting internal nodes
