Description

Creates an initial flow velocity constraint for a fluid flow analysis.

Usage

  1. Either press the toolbar button FEM ConstraintInitialFlowVelocity or select the menu Model → Fluid Constraints → Constraint initial flow velocity.
  2. Enter an initial flow velocity value for the analysis. The value is entered as a combination of the 3 main cartesian vectors components (X,Y,Z).
  3. For a 3D analysis, select a 'solid' (body) from your model, for a 2D analysis select a face.

Notes

In simple analyses, it is not necessary to specify the initial flow velocity, however it is recommended as best practice.
