Hi Rahul. I tried to implement what you said. I refined the mesh (Now I have 1 M cells running on 40 cores). I changed my dynamic mesh settings. Relaxed the remeshing settings. I have spring based smoothing (parameters set according to the reed-valve tutorial) and local face and local cell based remeshing. I also tried to activate implicit update (once in every 10 iterations with relaxation factor 0.5) but I don't see it getting reflected in the fluent transcript. The mesh update during the next time step is still taking too much time (approx 12 minutes). This update time is so slow when flow into the artery reaches the maximum. Do you have any other suggestions that I can try? Thanks in advance
