Trouble running hydrodynamic modelling

ref:  ERROR: Instability in THOMAS3D - ModuleFunctions - ERR10  

Dear Bentley Colleagues
I want to use grid size around 11 m and time step is 1 second to get stability (courant number). There is some trouble to running hydrodynamic modelling, it is about the device. If you have the supercomputer that can running my model to all simulation (sim7, sim8, sim11, sim12, sim13) big thanks to your helpful.
Note: I've send file name BenoaBayModelling.zip

Thanks
Regard.
