Boundaries

Fluid Body

The Fluid Body definition is used to define wall boundaries properties in an automatic way. Please note that the forces on fluid boundaries can be drawn in the postprocess. If necessary a new fluid boundaries can also be created. BOUNDARIES window can be accessed through Data>Boundaries>Fluid menu option or using the corresponding icon of the Tdyn toolbar.

The Fluid Body properties (see Figure 6) have to be applied to the front, bottom and back walls of the cavity (see Figure 7). For the two remaining surfaces without conditions we will use the “symmetry” option of the General Data menu (see below).
