Hello!
I had a quick look at your steering file. What you are doing seems correct to me, except that you also need to specify the concentration of the bed:
MUD CONCENTRATION PER LAYER
If you want to impose a stratified bed, you just need to specify
NUMBER OF LAYERS OF THE CONSOLIDATION MODEL > 1
In this case, you also need to specify the initial bed layers thickness by adding the user-subroutine: init_mixte.f in your FORTRAN FILE
You may also need to specify the concentrations (in %volume) at the boudary of the domain.
CONCENTRATION PER CLASS AT BOUNDARIES
The key word 'FORMULATION FOR DEPOSITION AND EROSION' is no-longer used. If you work with cohesive sediments, you will automaticaly be using the Krone and Partheniades formulation.
I hope this help! We are aware that the documentation of the cohesive algorithm needs to be updated. New test cases will be available in the new version.
Good luck, Cath
