Materials

Materials used in the problem and some complex boundary conditions are imposed through the Fluid Materials window (see Figure 4).

Fluid

The fluid properties of the problem are given through the Fluid Materials window (see Figure 5). In this example the fluid properties have to be assigned to the created volume (see Figure 7).

In the RANSOL list, density and viscosity of the fluid are fixed to 1Kg/m3 and 1 Kg/ms respectively (see Figure 5). The rest of the data is maintained at the value given by default.

Remark:

If necessary, new materials can also be created, by pressing the New Material button.

Figure 5 Fluid Material Window

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).

Remark:

Please note that many of the options have specific on-line help that can be accessed by moving the mouse pointer on them or by clicking with the right button of the mouse on them.
