Description

This keyword indicates the beginning of the material description. Each material-properties-block defines parameters and properties of the according medium. The first block refers to material number 00, 2nd block to 01, 3rd block to 02, and so on. The material numbers itself are assigned to elements within the mesh file (*.msh). Therefore, the complete input includes one block more as the highest material number given in the mesh file (because counting from zero). The description of one medium ends with the beginning of new block, i.e. #MEDIUM_PROPERTIES, or with the file input terminator #STOP.
