Porosities and Material Numbers

  Cells can be blocked within PHOENICS using either porosities (VPOR) or properties (PRPS); within FEMVIEW, each element can be associated with a material number. The interface program assigns all unblocked elements (i.e. porosity $\gt$ 0 or PRPS $<$ 100) a material number of 1. Fully blocked elements (porosity = 0) are assigned a material number of 100. Cells with a PRPS number greater than 100 are given a material number equal to the value of PRPS.

A FEMVIEW set of elements is created for each material found. The set name is MATnumb, where 'numb' is the material number. This enables blocked cells to be ignored when viewing the results in FEMVIEW, see section 4.3.
