Hello,
I am running an analysis of a steam turbine. I model the piping with manufacturer displacements at the nozzles (as I understand it - this effectively models this node as an anchor with movement).
When I view results I see that there are forces at this node but moments are all zero.
How can this be?
Can someone please explain this to me, or let me know what I'm doing wrong?
Thanks.

You need to set the rotations to ZERO. Blank displacemnts are FREE to rotate which is not the case for a nozzle.
