T-Rex: Automated Boundary Layer Meshing for CFD

What is T-Rex?

It is a technique for extruding regular layers of high-quality tetrahedra from boundaries. The tetrahedra can be recombined into prisms if you prefer. The mesh adjusts to convex and concave regions and colliding extrusion fronts.

Will my CFD code like T-Rex?

Yes. T-Rex cells are designed to minimize maximum included angles and cell volume ratios, which are two key characteristics for improved CFD solver accuracy. CFD results for an ONERA M6 wing in transonic flow have similar accuracy for T-Rex and structured grids, while the T-Rex mesh is much easier to generate.
