The order doesn't really matter. You can do it before or after setting up the mesh. In the end, to run an analysis you need both, the mesh and the setup.bernd wrote: ↑Wed Apr 17, 2019 2:31 pm Someone has added a nice picture to our FEM wiki ... https://www.freecadweb.org/wiki/FEM_Module#Workflow but IMHO it is wrong! It really makes sense to create the constraints BEFORE the mesh not after the mesh.
That was written by you, I think. I just formatted it. But it's free documentation! We can change the order if you want, no problem!The steps to carry out a finite element analysis are:
- Preprocessing: setting up the analysis problem.
- Modeling the geometry: creating the geometry with FreeCAD, or importing it from a different application.
- Creating an analysis.
- Creating a finite element mesh for the geometrical model, or importing it from a different application.
- Adding simulation constraints such as loads and fixed supports to the model.
- Adding a material to the analysis model.
The image is meant as a visual aid for those starting to use the workbench, to understand the general process. Of course, if you go into the details, you have many exceptions and steps that you have to follow to perform a good analysis. But that's including too much complexity in what is supposed to be a simple overview. You can edit the image as well.
True.
