Question:I am trying to use the specified displacement function to find the forces required (reactions at the nodes that I have specified a displacement) in order to cause a certain displacement of the piles
I want this to be part of a load combination that has two other static load cases in it. Therefore the reaction at the nodes will be the forces required to deform the piles when the other two loads are also applied.
I managed to do this before in a different model, but in the current model I am working on the specified displacement function is giving me the same reactions regardless of which other loads I combine with it.
Please could you let me know how to use this function properly?
Answer:
Basically, the specified displacements have to be part of the same Load Case (rather than Load Combination).
