Boundaries

Fluid Body

For this example we will use two different fluid boundaries. In order to do this we need to create a new boundary. This can be easily done by pressing the New Boundary button in the Boundaries window (see Figure 50).

 

Figure 50 New Fluid Body creation

In our case the values for both fluid boundaries have to be fixed as shown in Figure 50 for both Fluid Body and NewBoundary. This property has to be assigned to the boundaries of the geometry as shown in Figure 51.

Figure 51 Material and Fluid Body assignment

Note that the Fluid Body conditions used in this example could have been imposed by using only one boundary or by means of the Fixed velocity line condition. However the above definition can be used for different problems as will be shown in the next example.
