I'm trying to make blood flow analysis in a pipe which has 0.8 mm thickness with 50% contraction in the middle, as shown in the figure. I want to conduct two-way FSI in Fluent and transient structural. For the inlet boundary condition, I have an inlet velocity profile waveform that I successfully implemented it with UDF. My question is: In Fluent, my number of time steps is 740, the time step size is 0.001, and the maximum iterations per time step is 250. Since the settings are like that in fluent, how can i do the same thing in Transient Structural Analysis Settings Section? In my previous analysis attempt, i had set up the settings as shown in the figure but FSI coupling analysis didnt stop at 0.74 s at all and kept calculating.

Thank you so much Erik. It worked. 

One last question; I want to write cas. and dat file in fluent during FSI analysis. In Fluent I always do that with “During Calculation” , selecting time interval and datas. When I tried to do the same thing with FSI analysis, nothing’s been imported from fluent to desired file on my desktop. Is there a way to do that during system coupling two way FSI analysis? 

 

Thank you in advance.
