I know the usual solution is to make the material near the moment application points rigid. But, is there any way to apply moments while keeping the body deformable?
*Constrained_Interpolation is what you might be looking for the moment application without making the surface rigid. Here, the load application node becomes dependent while the surface nodes independent, thus won't make the surface rigid.
Pranoy Nair thanks for the reply. I tried this but the moments do not get applied (there is zero movement in the model)... I'm not sure if I'm doing it right. In the CONSTRAINED_INTERPOLATION card I make the load application node the dependent node, and chose a neighboring node as the independent node (both nodes are on tetrahedral volume elements of a deformable linear elastic material). I used 123456 for both the DDOF and IDOF fields. Can you shed some light on this issue? I'm not sure what is going wrong here.
Hi Adhitya Vikraman Subramani , the dependent node should be a free node (should not be connected your 3D mesh). Since the nodes of a solid element don't have rotational DOFs, the moments are not being applied to your model. Just create a free node near to the surface and refer its ID in the dependent field. Also, take more than two independent nodes from your surface mesh. I am sure RBE3 connections won't interpolate with one dependent to one independent rigid connection.
Let me know if you are still facing this issue.
