element solver (Abaqus Explicit 6.14) during the FSI analysis fluid and. If the sequence of various deformed configurations of the biological tissue over a cardiac cycle is available to the user, in that case, FlowVision can easily import those deformed configurations at the desired time points in the cardiac cycle and can smoothly interpolate the geometries between two consecutive time points. 1 Introduction Transcatheter aortic valve replacement (TAVR) has emerged as a. As with the IB method, the underlying computational grid in FlowVision is static however, unlike the IB method, this computational grid is generated by physically intersecting the initial Cartesian grid by the solid boundaries (SGGR method), thus providing the user with a perfect boundary conforming computational grid.īecause FlowVision works with a perfect boundary confirming grid, the wall shear stress on the surfaces of the deformable bodies can also be evaluated efficiently and accurately, just as in the ALE approach. Thanks to the underlying sub-grid geometry resolution (SGGR) method, FlowVision offers a unique, robust and reliable FSI solution.
