Using Density Gradient C_R_G(c,t), Pressure Based Solver
I am using VOF method in Fluent to model air-water bubble. I need to use the density gradient inside the bubble interface (where 0 < volume fraction < 1) to write one of the source terms in an equation.
But Fluent doesn't allow me to use "C_R_G(c,t)" macro as I am using Pressure Based solver.
Is there a way to make C_R_G work in pressure based solver using some extra text command or anything else?
Or anybody aware of any other macro to calculate density gradient in the cells in interface region.
I am experiencing exactly the same problem. Is there a way to calculate the density gradient in pressure based solver? Is there a workaround or something like that?
Thanks in advance.
