Hello I haven't found a similar problem and not too much information regarding FEM in FreeCad. I want to make an analysis based on a model designed in Sketchup, so I followed this steps:
1- Export model to STL file
2- Import model into GMSH and convert to INP file
3- Open FreeCad and create a new file
4- Import the new INP model into the FEM workbench
5- Create the Analysis and SolidMaterial
Here is where I get stuck, and I don't know what else to do; the moment I select a FEM constraint for a fixed... the model disappears. Any other force and it also disappears.
Is there any reliable way to get a model to FreeCad for FEM analysis? I don't want to make the model again in FreeCad...
PS: Sorry for bad english if so.
