Preparation of Geometry Models for Mesh Generation and CFD

Making geometry models suitable for CFD meshing is often a time-consuming bottleneck in CFD analysis. Here we will discuss why this is so and some ways to alleviate the problems.

Turbulence Model Influence on Flow in the FDA Benchmark Blood Pump

Computational fluid dynamics (CFD) can be used to influence decisions early in the design process. In order to assess the state-of-the-art of CFD and its predictive capability for medical devices, the U.S. Food and Drug Administration (FDA) developed two benchmark models for validation.

The Democratization of CFD

The traditional CFD process hasn't changed in 30 years, and the bulk of CFD done today (as much as 80% we estimate) complies with this accepted norm of creating a geometry in CAD, exporting it to a meshing tool, meshing it, setting up and running a CFD solver, post-processing results, going back into the geometry, altering it and continuing to do these design loops again and again.

CFD & Multiphysics Simulation

CFD simulates the flow of liquids and gases by performing millions of numerical calculations. CFD analysis is typically carried out earlier in the design process even before the first prototype is made. With high-speed supercomputers, better designs can be achieved quicker, faster, and cheaper. Multiphysics is advanced CFD involving multiple physics coupled to mimic the real behavior as accurately as possible.
