b3dinit.F

subroutine b3dinit

Description

Inializes physics variables on the 3D grid to default values then calls warmst to overwrite these if using values from a previously checkpointed run.

none

Order of Things

1. calls bset and uvzset to set initial scalars and velocities
2. calculates initial depth mean and depth varying currents
3. calculates initial water depths
4. initialises diffusivities,. adevection and friction parameters
5. inilialises spm sub-model
6. initialise pressure for compressibility term
7. calls warmst to read in checkpointed fields and overwrite these values
8. initialises any external code
9. find initial surface and river fluxes
10. initialises tide input routine
11. Set boundary proximity masks for ppm advection.
12. Initialise values for turbulent energy routine.
13. Initialise particle tracking.
