b3drun.F

subroutine b3drun (nfargs, fullargs, lfargs)

Description

This is the main control routine for the model code. It calls subroutines for domain decomposition, setting parameters, opening files and initialising variables. Then it loops through each baroclinic time step, calling the various calculation, output and boundary conditions subroutines. Finally it calculates timings and ends the parallel processes.

Subroutine Arguments

nfargs

fullargs Runtime/GUI arguments

lfargs

Local variables

i,j,k Local indices

icg,jcg Global indices

ierr Error flag ($\not=0$ for error).

iproc Loop over each of nproc processors

oddstep Determines order of directionally split advection routines. Alternates between $\chi$ then $\phi$, and $\phi$ then $\chi$.

timer1, timfact, timtot Timing variables

Global variables changed

oddstep, server, firstloop, looping, nbcs, tcount

Logical units

none

Order of Things

1. intialises parameters and run time arguments
2. opens files
3. initialises debugging
4. intialises domain (grid and bathymetry)
5. intialises model variables and restarts if required
6. loops through ndt baroclinic time steps
7. Calculates timing
8. ends parallel processing
