Materials used in the problem and some complex boundary conditions are imposed through the Materials window (access the Materials window as shown in example 1).
In this example the Fluid Properties have to be assigned to the created volumes. This is done by means of the Fluid Materials window. In the RANSOL list, density and viscosity of the fluid are fixed to 1 Kg/m3 and 1·10-2 Kg/ms respectively.
For every parameter, the respective units have to be verified, and changed if necessary (in our example, all the values are given in default units).
