open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi everyone !
I was wondering if there is a way in Sisyphe to mark the bottom particles regionally in order to know at the end of a run, which is the preferential origin of sediments and thus the behaviour of sediment particles according to their area of origin.
I would like to know the behavior of every particles and to avoid to use the same processing as for drogues (punctual particles)
Thank you !

Hi,
you have to add more sediment classes ...
www.researchgate.net/publication/3125295..._in_the_Bay_of_Brest
=> I investigated in the mentioned above study the change in sediment substratum nature by adding new classes of sediment: in this case the faeces and speudo faeces of Crepedula and also the sediment discharge of two rivers. So it was possible to analyse the discharge of sediment in the Bay of Brest and the settling of sediment due to the filtration-dejection activity of the benthos.

Cheers,
hope it can help

Hi flanagan, thank you for the answer. I didn't think about this method but i suppose it can fit ! I will try to add the different classes with the diameter via Bluekenue and to visualize their repartition with post processing.

In case of sediment mixture sand/mud, you will have to develop the model because in the standard version of SISYPHE only two classes are considered in case of mixture. So, if you have to have more than two classes and also sediment mixture the code have to be further developed like the example below:

Thank you but in my case i just want to work with different classes of mud with approximately the same diameters. I originally worked with one sediment class because it is relatively homogeneous.
