Webinar on the Influence of Meshing Strategies on Simulation Efficiency

FORT WORTH, TX (29 November 2017) – Pointwise, GoVirtual, and Metacomp Technologies will host a joint webinar entitled “The Influence of Meshing Strategies on Simulation Efficiency” at 10 a.m. CST (UTC-6) on 13 December 2017.

Meshing strategies have a direct influence on the accuracy and efficiency of CFD simulations. Once a meshing decision is made, it affects not only the types, number, orientation, and placement of grid elements, but also simulation stability, convergence, and accuracy. The mesh generation process therefore plays a critical role in providing accurate, timely results.

Using a marine propeller as a model, the aim is to better understand the relative merits and drawbacks of various meshing strategies. This webinar also focuses on simulation efficiency and its dependence on the mesh generation process.

The meshing strategies considered include two hybrid techniques and structured overset. An approach for computing simulation efficiency is introduced and the process for generating each mesh explored in detail. Best practices are highlighted with an emphasis on mesh quality, and the ease of surface and volumetric refinement. Each mesh is evaluated against the amount of time required to create the mesh, its cell count and quality, the accuracy of the results, and the time needed to run the simulation to a prescribed convergence threshold using CFD++ by Metacomp Technologies.

Topics covered include:

  • Defining simulation efficiency
  • Resolving highly curved surfaces using anisotropic refinement
  • Automatically generating hex-dominant and prismatic boundary layer meshes
  • Structured overset meshing considerations
  • Numerical setup and post-processing using CFD++
