Wall shear stress and pressure patterns in aortic stenosis patients with and without aortic dilation captured by high-performance image-based computational fluid dynamics
Fig 2
Simulation domain Ωsim and the embedded subset of interest ΩCT.
The ΩCT includes the segmented model geometry, all velocity and pressure support data are applied over fringe zones outside of ΩCT, as volumetric patches attached to the inlet and outlets of the model. The flow equations are then solved for the whole Ωsim. The blue window which is magnified on to the right side of the simulation domain shows the spatial resolution represented by thin mesh lines on the surface.
