FEM ConstraintFlowVelocity/de

Beschreibung
Applies a flow velocity as boundary condition to an edge in 2D or to a face in 3D.



Anwendung

 * 1) There are several ways to invoke the command:
 * 2) * Press the button.
 * 3) * Select the option from the menu.
 * 4) The task panel will display menus for constraint flow velocity
 * 5) Select the target Edges or Faces.
 * 6) Press the  button.
 * 7) Deselect "unspecified" to activate the necessary fields for edition.
 * 8) Fill in the values in mm/s for the main Cartesian components.

Hinweise

 * Vector components that are ticked as "unspecified" will be interpolated by the selected solver.
 * Any vector that should be the result of the solver must be ticked as "unspecified".
 * If the target face or edge is not aligned with the main cartesian coordinate system, it is possible to tick "normal to boundary".
 * If "normal to boundary" is ticked, the normal vector to the selected edge or face is X and it will be oriented away from the mesh domain.
 * For example, if a flow of 20 mm/s of air must enter the domain, then after ticking "normal to boundary" the user will have to input -20 mm/s in the "velocity X" field.


 * For a Wall with non-slip condition, the flow will be (0,0,0).
 * For a Symmetry condition, the flow will be (0, Unspecified, Unspecified) if "normal to boundary" is ticked.
