FEM: Element names and Nodes

Postby Zig_mint » Thu Jan 10, 2019 5:59 pm

Hi,
PS: This is my first post so apologies if I sound dumb.

I wanted to know if there is a way by which I can store all the node numbers and element numbers of a mesh, which was in turn made for geometry by the mesh tool. I want to use the node and element tags for further processing with my algorithms. I want to store the data in a CSV file, which i can later use.

welcome to the world of FreeCAD :) Try this:

Code: Select all

doc = FreeCAD.open(FreeCAD.ConfigGet("AppHomePath") + 'data/examples/FemCalculixCantilever3D.FCStd')
mesh = doc.Box_Mesh.FemMesh
mesh.Nodes
for e in mesh.Volumes:
    mesh.getElementNodes(e)
