## Description

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

## Usage

or choose Model →Fluid Constraints→ Constraint initial flow velocity from the top menu.

- 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).

## Limitations

- The constraint applies the initial flow velocity to all nodes in the FEA model.
- The constraint cannot be oriented other then using the main cartesian components.

## Notes

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