Hi and welcome to the world of FEM.If you would like to work with FreeCAD FEM it is highly recommended to use the latest development version 0.17.x You can download it here: https://github.com/FreeCAD/FreeCAD/releases It is what all users and developers of FreeCAD FEM do because there have been tons of fixes and changes in 0.17 in FEMjohnsmith wrote:Version: 0.16.6706 (Git)
It is difficult to say what it the right way to go for your model because we do not know your mode. Best results you will get if you make a boolean union of all solids and extract the solid out of this compound union. This is the best for most models but might not be suitable at all for your model because you model might has its own requirements. Best is to post the FreeCAD file of your assembly model.johnsmith wrote:I have 7 solids that I have positioned with the assembly2 workbench. I combined them into one object using the Part Workbench's Make Compound tool. When I start to process of making a mechanical analysis, I get the mesh creation dialog ("Tet Parameter"), and when I press OK, it seems like it will never end. It just sits there using a full CPU core, and 5-10GB for RAM. I have 16GB of RAM, so that's fine, but I have a feeling it's trying to create a mesh more complex than practical.
What exactly do all the "Tet parameters" mean, and how can I modify them to speed up the mesh creation process?
cool link But as johnsmith is a beginner I would highly recommend to use second order tetra10 (10-node tet-elements) elements onlyr-frank wrote:For meshing we have different types of elements and different options for meshing. https://www.comsol.com/blogs/meshing-yo ... ent-types/ ...
