Did you ever use ANSYS to evaluate Euro Code compliance of a silo / a structure? Idea is have some basic loads ( pressure, weight, wind, earthquake ) and starting from them evaluate al long list of combinations. Coefficients and combinations are clear, this is not the topic of this post.
If I have 100 combinations I can duplicate 100 times the static structural and setup each one with all the needing basic loads multiply by the correct factors. It work but it is vvery long way.
I seen on tutorials ( is here: ) that it is possible prepare 1 substep for each basic single loads ( alone without the others and after that, thru the APDL command console writting some code that formalizile how to scale is basic loads and what to add together.
It work: displacements and loads on fondations are indicated but stress is always zero. I don't understand why...
Franckly speaking I don't think the solution combination proposed by ANSYS is correct because this way kills all the not linearity of the system, so for example on nozzle where are reinforcing plates with a frictional contact we don't will evaluate the real situation.
Some advise?
