The functionality of this routine is now expanded so that for evey time step the element materials are read in. The code for determining the material file names and opening the file name and then reading in the element files is placed in the same code that the age grids and velocity files are processed. Obviously, reading in materials currently only works for Full; fill be working on Regional next.
