Improving artificial valve design is of paramount importance considering that bio-prosthetic aortic valves still present several limitations associated with their hemodynamic performance and durability. Numerical simulations allow for an accurate analysis of strain and stress distribution, which is fundamental to estimate mechanical and hemodynamic performance of a medical device. We present two embedded approaches for high-performance numerical simulations of hyperplastic solid structures embedded in laminar, transitional, and turbulent flows. The numerical results presented in this work provide insights into the performances of bio-prosthetic aortic valves.
