Hello,

I'm trying to simulate a flow of a liquid (diesel fuel) through a very narrow ring gap under extremely high pressure, i.e. 3000 bar. The field of application is fuel injectors.

My question is - how do I set a dependancy of density and viscosity on pressure? At 3000 bar, the liquid can no longer be assumed incompressible.

Is it done in material properties, like the dependency on temperature or is it something else?

Thanks a lot and have a nice day
