In ANSYS 2 way FSI guide, they input the value of the force in transient structural setup bloc. while they do not mention that in the fluid side ( Fluid fluent) even that we identify the Inlet.
So according to your experience with this type of problems how would you consider for treating it?
Dear/Mohammed
Referring to the following Paper that includes more detail about how to treat transient pressure force in 2 way FSI.
Ahmed Abdelhameed Thanks Sir, I read the paper but still have one point that I am not sure about ( The pressure Load should be or not ? applied in the structure side ( Transient Structural Bloc) because if we applied that there so what is the difference between a solo transient structural analysis and 2 Way FSI, yet in the ansys manual they say the same of what I said but they apply the pressure in the structure side .
As far as i understand your problem i would suggest to simplify the problem by solving as follows:
1-Assume steady state condition.
2- Use one way at the beginning.
3-Apply 2 way.
4-It will be reasonable if you validate with experimental data.
5-If the differences are irrelevant you may ignore the effect of transient case.
6-If not, try to simplify the transient value of pressure force or you may solve the problem using fluid effect only.
My best wishes
