SAICHENTHUR OFFLINE Senior Boarder Posts: 83 Thank you received: 7	Hi all I tried to run sisyphe with hydrodynamic file as input. I am getting the warning that THE PERIOD OF COMPUTATION IS NOT A MULTIPLE OF THE HYDRODYNAMIC FILE PRINTOUT PERIOD. THE LENGTH OF COMPUTATION WILL THEREFORE BE 45000.00 SECONDS But my simulation is for 15 days and the hydrodynamic input is also there for 15 days How to fix this?

Hi,

Some comments about your steering file:
- it's preferable to use coupled approach between hydrodynamics and sediment, especially for suspension process which is better represented with a Telemac-2D/Sisyphe coupling
- you should keep the default value for CRITICAL EVOLUTION RATIO. With such a high value, you allow the model to compute unreal bed evolution. A value of 1 should be enough
- you provide a bottom friction coefficient, but no associated law
- BED-LOAD TRANSPORT FORMULA = 11 is not possible (I believe)
- CRITICAL EROSION SHEAR STRESS OF THE MUD has the dimension of the NUMBER OF BED LOAD MODEL LAYERS (i.e. 1 from your steering file). So your second value (100) will be useless.

Maybe you should consider only one class first, before considering a mixed approach.

I hope it helps.

Regards,
Laurent
