Abstract: A transformation electromagnetics-based approach is presented to facilitate the use of fixed Cartesian grids for modeling arbitrarily shaped (convex or nonconvex) curved boundaries in finite ...

Abstract: The accuracy of the Cartesian grid method has been explored for the 2D compressible Euler equations. We prescribe wall boundary conditions at ghost points near embedded boundaries by using ...

Automatic mesh generation, recognized as the “Holy Grail” of Computational Fluid Dynamics (CFD), was highlighted as a critical objective in the NASA CFD Vision 2030 study. Adaptive Cartesian grid ...
