Описание

Устанавливает скорость потока в качестве граничного условия к кромке в 2D или к грани в 3D.

Constraint flow velocity menus within the task panel

Использование

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

Notes

  • 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.
