Problem with convergence in mesh independence
Hello there I have created an assembly of knee joint by 3d scanning of knee joint parts. Imported these parts into creo and assembled them. Then transferred these parts to ansys 18.1. Now the problem is that during mesh independence study, my results are not converging. I gave fixed joint constraint to the knee joint between tibia and femur and also between femur and patella. Then I started reducing the mesh size at the joints. But the trend of values is very bad when a graph is drawn. Any ideas related to it? I attached the assembly picture in the file.
