Hi,
is it possible to combine two loadsteps? In the first loadstep I want to apply a pressure as a linear static problem and in the second loadstep, I want to apply a force as a nonlinear quasi static problem. How can I combine these steps?
Yes, it is possible.
I don't know if i got you right, but you might do the following:
- create two (or more) loadsteps
- create the things you need for optimization
- when choosing a response, take the 'weighted version' - e.g. weighted displacement or weighted freq.resp.. Then you have to input the values for the weight of each single loadstep.
Did that answered your question?
Combining linear loadcase is possible using LOAD card in Optistruct.
In hyperview we have option for derived loadcase or superposition of loadstep.
