open TELEMAC-MASCARET The mathematically superior suite of solvers

Good afternoon,

I am doing a simulation in a sedimentation well, but I want to enter a granulometric curve of suspended sediments (as shown in the attached SIS.cas). And I want to enter a total concentration at the beginning of 0.0001426 (0.395 gr / l), but when entering this value I get a value of 0 for each sediment class at the beginning of the model (as shown in the graph). The granulometry of the sediment comes from a hydrometer test.

I performed a simulation with a single representative d50 and obtained the appropriate value at the beginning of the model. However, with granulometric curve, what modification should I make?

I hope obtein some recomendation.

Thanks
