This work documents a new method for rapid and robust Cartesian mesh generation for componentbased geometry. The new algorithm adopts a novel strategy which first intersects the components to extract the wetted surface before proceeding with volume mesh generation in a second phase. The intersection scheme is based on a robust geometry engine that uses adaptive precision arithmetic and which automatically and consistently handles geometric degeneracies with an algorithmic tie-breaking routine.doi:10.2514/2.464 fatcat:msjd6wxfxrd6pppzui7stijoau
