Within CFD workflow, surface geometry clean-up and grid generation are bottlenecks, because they often require weeks of manual labor. Building on previous results, we proposed an automatic and fast grid generation method for Navier-Stokes computation that can handle defective solid surface directly as input, that is, without prior clean-up.
