Abstract: | An important element of global software codes for computing real-life three-dimensional problems with singularities (such as boundary and internal layers, shocks, detonation waves, combustion fronts, high-speed jets, and phase transition zones) is automatic adaptive grid generation, which can considerably enhance the efficiency of computer resource management. In three-dimensional domains with boundaries of complex geometry, in particular, with discretely defined boundaries, adaptive grids are generated by applying inverted Beltrami and diffusion equations for a spherical monitor tensor. |
