Gel and sand

      Hi all. Previously, I modeled water with sand in Fluent. I pumped sand fractions into the water. Please tell me how to make gel instead of water? I would like to have a gel and mix sand fractions into it. Gel is a non-Newtonian fluid.

      In much the same way as water. Alter the material properties, and set the viscosity via one of the nonNewtonian models. Note, these are only available when the system is laminar.

        Thank you! What is the best non-Newtonian model for gel?

      It depends..... Which one best fits your data for the shear range of interest?

        Good

        do I need to know the shear range of the gel?

        what other data is needed to determine the model for the gel? I will need to request them from the supplier.
