Hello Everybody,
In order to implement a controller within the ANSYS programm, I need to have access to the acceleration of a node and the force acting on an element. I know how to do this in the postprocess, but I couldn't find any helpful command to do it during a simulation (within a DO-loop)
What I found so far:
*GET,x1,NODE,10113,U,Y => results in the displacement in Y direction of node 10113
*GET,F,NODE,10113,F,FY => results in the force acting in Y direction on node 10113
the DERIV command doesn't work here. Also I think doing the derivation manually is not a really nice solution.. but a backup idea. I hope someone has a better approach.
Does someone have an idea how to solve this problem? The *GET command doesn't future the force together with 'ELEM' and I also couldn't find a A instead of a U to get the acceleration.
Thank you for your help.
Regards
Raphael
