How do I rotate a meshed body?
How do I rotate a meshed body?
(OP)
I have a model of a door that has been meshed and the simulation is ready to run. After that simulation is run, I would like to rerun the simulation a few more times with the only difference being that the door would be open at a few select angles. My preference would be to not have to remesh the entire model just to change the orientation of a few parts in the model. Is there a way to rotate meshed parts without essentially starting over with the mesh?

NMODIF might do the trick for you.

Is there a way to do that from the Mechanical UI, or do I need to edit the model in the APDL UI?
Additionally, since this is specifically for nodes, is there a way to communicate that all the nodes in a given part (or even better yet, named selection) need to be rotated at once?
Finally, it looks like this only allows rotations around the global coordinate system, which would require a rotation followed by a translation. Is there a way to use a custom coordinate system?
Thanks for the help!
EDIT: I just saw the "Node Move" button in the Mechanical UI, but it looks like that is intended for tweaking the location of individual nodes in order to improve the quality of the surrounding elements. If I could move nodes in mass, this command might work, but otherwise, it looks like it's not an option.

NMODIF is an APDL command that you could used to modify the node location. A suggestion would be to create a script to identify all the nodes of interest and re-position the nodes. It can be defined with an active coordinate system.
Another method worth exploring that might be easier is assembly inside Workbench. Example here: http://engr.bd.psu.edu/ansysug/Model%20Assembly.pdf.

and then locked during the analysis. Without seeing the geometry it's hard to know if this works in your case.

When I looked into it a while back, the Assembly Manager ACT was a non-free ACT. I can't find it on the Ansys App Store today.
