A Stable Condition and Adaptive Diffusion Coefficients for the Coarse-Mesh Finite Difference Method
Coarse-mesh finite difference (CMFD) method is a widely used numerical acceleration method. However, the stability of CMFD method is not good for the problems with optically thick regions. In this paper, a stability rule named the “sign preservation rule” in the field of numerical heat transfer is e...
