Announcements Pointwise and Applied CCM will host the webinar, Mesh Strategies for the FDA Benchmark Centrifugal Blood Pump on 1 October 2019 at 10 a.m. CDT (UTC -5).

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.

Sponsor CFD Review

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.
