Materials

Materials used in the problem and some complex boundary conditions are imposed through the Materials (Fluid) window.

Fluid

In this example the fluid properties have to be assigned to the created surface. This is done by means of the Fluid Material window. In the RANSOL list density and viscosity of the fluid are fixed to 1Kg/m3 and 7.143 10-6 Kg/ms respectively (see Figure 69).

Figure 69 Fluid properties and initial values

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).

Boundaries

Fluid Body

For this example we will use the two fluid bodies defined in the previous example and the characteristics of both fluid boundaries have to be fixed as shown in Figure 70.
