Schematic of fluid/solid interaction algorithm and boundary conditions (BC). Each iteration followed this process, Step 1: Simulate the fluid flow in the AV canal with no slip velocity BCs along the fluid/solid interface and a pressure drop, ΔP = Pin - Pout, across the canal. Step 2: Transfer the pressure and wall shear stress loads from the fluid model to the cushion surface using the 1D surface elements (black dashed line). Apply displacement BCs to myocardium as shown. Step 3: Calculate the elastic stress and inelastic deformation for a set time of growth and remodeling, and then remove load. Step 4: Update the fluid mesh using the new relaxed cushion geometry. Repeat Steps 1-4.
