MeshED-101 | The motorbike geometry from OpenFOAM tutorials

Video Description

This is a step-by-step video, 2 hours long, unscripted live session, where anything can go wrong. In this session we compare the mesh generated with snappyHexMesh with a mesh generated using EnnovaCFD (using a topology-based meshing method). We also run the simulation using EnnovaCFD and WSL.
