Resolving Boundary Layers with Unstructured Quad and Hex Meshing: On-Demand Webinar
All things being equal, CFD practitioners prefer to use hexahedral mesh cells in the boundary layer for the improved robustness and accuracy they bring to the flow solver. Traditionally, a hex grid would be created using a structured grid technique … Continue reading

The Handiest CFD App – the Y+ Calculator
The Y+ Calculator app is a handy tool for calculating the grid spacing to achieve a target y+ value for viscous computational fluid dynamics (CFD) computations. Simply specify the flow conditions, the desired y+ value, and compute your grid spacing. … Continue reading

Survey Results: Mesh Types, Part 2
The Mesh Types survey included several questions with short-form answers and we shared that data last month. Here we have answers to the long-form, open-ended question about what types of meshes you said you wanted to generate. So let’s start … Continue reading
