The high performance computing enabled Fluid Dynamics Solvers (P-FLOW) facilitate the modeling of realistic physiological and pathological biofluidic scenarios in the presence and absence of vascular implants. The stationary and transient Navier-Stokes and Stokes equations are efficiently solved using either a finite element method with Schur complement preconditioning, adaptive time-stepping, and tunable stabilization or a finite volume method based on a smoothed pressure correction algorithm. Both solver types rely on platform-independent fast parallel processing, runtime solver monitoring, and advanced convergence criteria. Watch the demo video!
Blood flow and wall shear stress (WSS) as a function of flow diverter stent placement.
A set of standard boundary conditions and specialized boundary conditions for realistic blood flow modeling (e.g., developed flow, Windkessel model) can be applied and arbitrarily transiently modulated. Initial conditions based on experimentally measured data can be imposed. Easy extraction of key parameters like wall shear stress and powerful visualization tools complement the intuitive and efficient workflow.
The solvers are comprehensively and continually validated by comparison with analytical solutions for selected problems and benchmark problems. Comprehensive documentation is available for Sim4Life.
