Fluid properties

Submitted by Carlos Guamushig on Tue, 12/02/2014 - 17:43

Hello everybody,

I need to know how I can modify the fluid properties in an CFDEM simulation. I changed viscosity and density but after running the simulations I have got the same answer in different fluids with the same granular material.

Regards,

Carlos

Hello Carlos,

I think you should tell us more,

I am trying to evaluate different fluids interaction between a sort of granular material in order to do that I need to change the fluid properties. For instance, I need to change water to oil but I do not know which parameters are needed to modify.

Regards,

Carlos

You should change nu in constant/transportProperties, the density is defined as rho in the 0/rho file and the gravity is in constant/g file. Those are where you can control the physical properties of the fluid.
