Is it possible to add custom materials to the material library?

Hi,
I would like to define a new material for a CFD problem. I want to define a fluid, and enter the physical properties (density, and viscosity). The fluid is non newtonian too. Is it possible to add a custom-defined fluid?

Thanks,

@dalejarias, sure - you can add all physical properties of the fluid you want to simulate. E.g. for incompressible flow, this looks like this:

For compressible flow you have a bunch of more options:

What are you planning to simulate?
