I am running a tet4 model that is connected to the load application point as shown on the figure. I ran two models, Linear and non-linear. There’s a significant load applied at node 1 and its connected to the tet4 model with RBE2 connection (shown on the image). In the linear run, my displacement at Node 1 is around 0.16in and for non-linear run, this is magnified to 5in. That’s a huge difference between linear and non-linear models. The stress levels in the solid model have not change drastically as the deformation on node 1. Could this be anything to do with the MPCs are connected to the solid model?
