06.Set the Boundary Conditions

Set the boundary conditions.
The flow velocity is given at the input opening and the velocity potential is given at the output opening.

 

  • The details are explained at [Fluid] tab of the boundary condition.

 

You need to set boundary conditions on some parts of model's body (topology).
It varies depending on the analysis.

The boundary conditions are distinguished by name. It is not allowed to assign the same name to the different boundary conditions
 

Procedure

  1. On the [Model] tab, go to
    ,
    and select [Select Face] on the drop-down list at .
     

  2. How to Switch the Object to Select
     

  3. Concept of Body and Topology
