CTH reader: derived density is not computed
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The CTH reader computes the material densities for each material, but not the average density. Note that the average density is not computed by averaging the material densities, but by summing the mass of each material in a cell and dividing by the cell volume. If void is present, the volume of the void has to be subtracted from the cell volume before computing the density. See the code in bug 0011960 for details on the computation.
