NSTART
+
Starting time step - used to skip through the boundary condition data
file for restart.
-
Read starting time step from HOTSTART file
3
NCYC
+
Number of time steps to be simulated.
4
DELT
+
Initial length of a time step (hours) OR the time increment (hours) for
this step of a dynamic simulation.
5
TMAX
+
