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 domain of RTE is discretized by unstructured meshes; an angular direction of RTE is ACTIVATED CHARCOAL PEPPERMINT discretized as a set of contrast angles by structured quadrilateral meshes.Then, both spatial domain and angular direction are coupling solved by DSEM.

However, this coupling solution leads to a large-scale matrix problem.To address this, the element-by-element sweeping strategy optimizes the ordering of Splash Mat unstructured spatial elements.Several examples are provided to demonstrate the effectiveness of DSEM with the element-by-element sweeping strategy.

Compared to the original sweep strategy, the element-by-element approach significantly improves calculation efficiency and reduces computational time.
