摘要
A method for solving space-time problems involving three-dimensional spacewherein an unstructured four-dimensional finite element model is generated andsolved to produce a four-dimensional solution. The four-dimensional mesh isgenerated from a three-dimensional mesh by extruding each of the simplices ofthe three-dimensional mesh in a time dimension. The four-dimensional prismsformed by extrusion of the three-dimensional simplices are divided into aplurality of four-dimensional simplices which form a four-dimensional finiteelement model. The elements of the four-dimensional model can be selectivelyrefined to obtain a finer mesh in areas of greater interest, and a coarsermesh in areas which are of less interest. The mesh can be refined in thespatial dimensions and also in the temporal dimension.
