For the incompressible simulation, the user does not need to specify the material properties, as the material density is solved as part of the equation of state. 

​

The user should specify a constant material density and viscosity. The picture below shows the general materials data preset in the SimScale. If the desired materials are not in the list, the user should choose air and change the kinematic viscosity and density in the space.
