Releasing a forced displacement
Releasing a forced displacement
(OP)
In NE Nastran the SPCD command will enforce a displacement on a node. In a non-linear run placing the SPCD command in a SUBCASE and then removing it in the next SUBCASE results in the enforced displacement being ramped down leaving me where I started. My goal is to remove the enforced displacement simply be removed and the structure then find it's free state. There is contact in this model.
Does anyone have an idea as to how to remove the SPCD displacement without having it ramp back to zero?

Basically, anything you can do in the text editor can be done in FEMAP buy sometimes it's a bit more complicated. On the other hand, if you use Analysis Set's you only have to do it once. There are Pros and Cons to both methods.
