help: How define the sand's density

I am making simulation of water and sand two phase flow by fluent. how define the sand's density? the wet density or the dry density?
If density is set the wet density(2650),the residual is not converged. when density is set the dry density(1500) ,the residual is converged.
thank you very much!

how do you define sand density for it?
you know that you shoud at first select water in fluent databasa at define/material and copy and rename it,then change the copied density from 998.2 to 2650.and change/creat.then at define/phases you should define water as primary and sand at secondary phase. in sand window select granular and define the diameter of sand and other informations.
If you did this and it does'n converge, then I think that the problem is from another things not density.
good luck dear
