I have been making the water and sand two phase currents the computations, ask when in fluent defines the sand, the density how defines? Is with the dry weight density or the wet density? How does the coefficient of dynamic viscosity give?

It is hard to understand your question. Why don't you just put in a value for sand density (i.e 2500 kg/m3) and see what happens?

reason: 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.
