2-way FSI, Fluid domain does not deform
 

HI all,
Sorry if this question is kind of Naive.
I have done FSI with transient structural and Fluent.
It converges after playing with some settings. The problem is that only the solid domain deforms in result file. I have set the whole fluid domain and even all wall boundaries as deforming. But animating the results, only the solid domain deforms.
Do I need to select also the remesh in the setting?
What am I missing?
