EqualDOF mp constraint

Post by a20145878@pucp.pe » Fri Feb 07, 2020 5:25 pm

Good evening,
I have a problem with the assignment of master point and slave point for a rigid diaphragm. When I use the mentioned command, everything is right. However, when I run the analysis, there is a python error in the terminal in which point out "Different NDF on same node". I think that could be a problem in the definition of the interaction, though do not know where and I appreciate you help.
Thanks in advance

Are you using a rigidDiaphragm in a 2D problem? If that is the case, you can't. RigidDiaphragm only work in 3D. The 2D counterpart would be an EqualDOF in Ux

If this is not the case, can you post your SDF file here? We will have a look.
