Beschreibung
This tool converts surfaces of 3D elements of a selected FEM mesh to mesh or converts 2D FEM mesh to mesh. Internally, it picks FEM mesh element faces that are unique (not shared by two elements) and uses them to create faces of a mesh. Optionally, it can be used to save a deformed mesh. This is done by adding the displacement of the FEM results to the mesh nodes (the scale of the displacement can be set using Python).
Anwendung
- Ein FEM-mesh-Objekt auswählen
- Optionally also select the FEM results.
- Es gibt mehrereMöglichkeiten den Befehl aufzurufen:
- Die Schaltfläche FEM-Netz zu Netz drücken.
- Den Menüeintrag Netz → FEM-Netz zu Netz auswählen.
Skripten
Note: The parameter scale was introduced in version 0.21. For older versions of FreeCAD omit it from your code.
The cantilever example:
from os.path import join
import FreeCAD as App
import Mesh
from femmesh import femmesh2mesh
path = join(App.getResourceDir(), "examples", "FemCalculixCantilever3D.FCStd")
doc = App.openDocument(path)
fem_mesh = doc.Box_Mesh.FemMesh
result = doc.CCX_Results
scale = 1 # displacement scale factor
out_mesh = femmesh2mesh.femmesh_2_mesh(fem_mesh, result, scale)
Mesh.show(Mesh.Mesh(out_mesh))
