This post is a continuation of the vignettes that I started few weeks back with the Computational Fluid Dynamics theme. The vignette demonstrates how to create a CFD mesh in the 3DExperience platform. Majority of CFD pre processors require an air tight or water tight CAD geometry to create even a simple CFD mesh. The 3DX pre processor hex dominant mesh tool does not require any CAD for fluid meshing. Rather fluid domain definition in itself is sufficient to generate a high quality CFD mesh.
