Dear experts
I have a laser scan from 1M barrel reservoir tank which was in service for 20 years. This led to some spatial dislocation in some points of the tank which demands FEM analysis for the sake of FFS (Fit For Service). Therefore, I have to define spatial displacement for the tank which leads to stress. Then, I want to put the liquid inside and see if the tank can tolerate the pressure or not!
now the question is here:
How can I define the new location of the nodes?
Thanks a Million

You can have the analysis divided into two parts:
Step 1: displacement boundary condition at deformed locations;
you could propagate step1 into step2 to make sure the deformed location remain intact.
If however you can't find the location using your GUI, use getByBoundingBox(...)
Step 2: internal pressure analysis.
Hope this helps!
