Unphysical solidification

Thomas

I am running two phase simulations of sand in water. Clearly the accumulation of sand has a different time scale than the features of the fluid flow (flow direction, turbulence). So my question is if there is a way to solidify, i.e set a high PRPS value or high viscosity value in each cell reaching a specified volume fraction of sand or specified density.

This could be done after a restart when the "steady state" fluid flow is reached, and the development of a sand dune is mainly dependent on the supply of sand. Setting a new surface based on the density distribution and then restart to get a new flow pattern would speed up the computations of a process which takes several hours in real-time.
