-A consequence of the way binary input files have been implemented in \mf, simulated dependent variable binary output (for example, head and concentration) cannot be used as binary array input for a model. Instead, simulated dependent variable binary output must be processed and split into separate binary files for each layer or combined into a single three-dimensional array.
+A consequence of the way binary input files have been implemented in \mf, simulated dependent variable binary output (for example, head and concentration) cannot be used as binary array input for a model. Instead, simulated dependent variable binary output must be processed and split into separate binary files for each layer or combined into a single array equal to the size of the grid (for DIS grids this would be an array equal to NCOL * NROW * NLAY).
