    Please help: How to generate a node in CAE?

    Hi, Rob: Thanks a lot for the reply. I am using a simplied model (a ball and a plate) to represent the real model. Although I used your method to define the contact, still got the same problem (too many attempts). Please note the Z-direction distance between the ball and the plate is 0.5...

    Please help: How to generate a node in CAE?

    Thanks, Corus. I added two opposite concentrated forces at an unimportant area to simulate the moment, looks good. One more question: I want to simulate a contact on two shell surfaces (composed of many triangles). The shells should have thickness (to simulate 2mm cartilage). Right now I use...

    Dear all: I have a stl model of a femur and need to add a layer of cartilage on the femoral head. Since the stl model is composed of a lot of small triangles, thicken those triangles (altogether) will have normal problem. If I thicken the triangles one by one (hundreds of them), it will end up...

One more question: I added a moment load onto a node, but an error message came out: 1 node have inactive dof on which boundary conditions are specified". The node is the one I added moment. My model has tet mesh (only choice since...
