A. Above Problem: What is the larger number of iterations, do you mean to increase the number of iteration on the fluent side, generally, I kept the iteration around 250 on the fluent side and for FSI is around 5 time step (both fluent and structural models are steady and static).As the load is ramp up for each time step, is it fluent iteration or FSI time step maximum iteration in coupling system to increase which one?
B. Doubt about FSI: I am currently involve with the steady and static 2-Way FSI, I just put the time step in the coupling system 5 with maximum 5 iteration. I am not sure, if we use the static strucutural should we use only the 1-time step with n-number of maximum iterations? sometime, when I re-run my fsi model, it give me error that the time step must be higher than earlier one. I feel bit skeptic since each time step of coupling, the static load will be ramp up and then the information will be exchange between the fluent and vice versa so. I am not sure, if I am right, I tired to dig the manual for the system coupling, its difficult to get the theory behind it any suggestion?
