Join us for a live webinar on 13 December 2017 at 10:00 a.m. CST (UTC -6) during which we will explore the topic of identifying the best type of mesh to use for the fastest and most reliable CFD simulation.
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. Also, this webinar focuses on simulation efficiency and its dependence on the mesh generation process.
The considered meshing strategies 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++
