BG_Flood

The main code workflow is as below. The user specified param file is read and that guides whether the code runs a double or single precision simulation. once the model is setup either the code goes ahead the main loop or goes through a test which either applies to the simulation already initialised or totally independant (which test depends on what is done).

Main work

The main work function deals with initiallising and preparing a simulation.

CPU vs GPU

the model is automatically setup on the CPU first and then copied on the GPU for the rest of the simulation.
