A sweeping algorithm of unstructured elements in discontinuous spectral element method for thermal radiation in irregular multidimensional geometries
The discontinuous spectral element method (DSEM) coupled with an element-by-element sweeping strategy is proposed as a solution to the radiative transfer equation (RTE) for participating media in irregular geometries.In the solving processing, a spatial Frying Pan domain of RTE is discretized by unstructured meshes; an angular direction of RTE is d
