Webinar on Mesh Strategies for the FDA Benchmark Centrifugal Blood Pump

FORT WORTH, TX (9 September 2019) – Pointwise and Applied CCM released the webinar, “Mesh Strategies for the FDA Benchmark Centrifugal Blood Pump,” that explains how hybrid-viscous mesh can improve solution efficiency.

To watch the webinar, go to:

The focus of this work is to explore hybrid and multi-block structured meshing strategies and their impact on solution accuracy for a Food and Drug Administration (FDA) benchmark case involving a centrifugal blood pump. If no appreciable change in solution accuracy is observed per each meshing strategy, hybrid meshing techniques may facilitate a more efficient solution process. Designed to operate across a large range of flow conditions, the blood pump consists of four blades attached to a rotor base and shaft.

Pointwise has numerous integrated functionalities, making hybrid-viscous mesh generation fairly automated - reducing the time required to construct a high-quality mesh. These tools enable the engineer to focus a majority of their time interpreting simulation results. Consequently, this allows the engineer to make decisions rapidly and early in the project life cycle.

Caelus v8.04 [2], a derivative of OpenFOAM, was used to perform the CFD simulations on each of the grids for solution accuracy comparisons.

Discover how to:

  • Utilize anisotropic tetrahedral extrusion (T-Rex) to automatically generate a hybrid-viscous volume mesh suitable for internal flow applications
  • Enable surface mesh adaptation for proximity refinement during volume meshing
  • Construct a suitable multi-block structured mesh topology
  • Thoroughly examine surface and volumetric cell quality
  • Set up an MRF simulation using Caelus and interpret simulation results to identify key parameters driving solution accuracy

Presenters will be Joshua Dawson, Travis Carrigan, and Daniel LaCroix, Ph.D. from Pointwise, Inc. and Chris Sideroff, Ph.D. from AppliedCCM.
