Far Field

Simulate fluid flowing past the part in an unconstrained environment.

This condition is also commonly known as the freestream condition. The farfield condition permits fluid flow to either enter or exit the selected surface depending on the local flowfield evolution. Typically, the flow crossing a farfield boundary is quiescent and has a known constant velocity (magnitude and direction). Use this condition to model incoming and outgoing flow at the fluid domain boundaries that are placed far away from any strong flow disturbances. It is not recommended to use this condition on surfaces that are in close proximity to regions of strong flow disturbances.

First, you must create a fluid domain around an embedded solid part.
  1. On the Fluids ribbon, select the Far Field tool.

    Tip: To find and open a tool, press Ctrl+F. For more information, see Find and Search for Tools.
  2. Select one or more surfaces of the fluid domain.
  3. In the microdialog, define the temperature, velocity, and direction of the fluid in the far field.
    Tip: The directional fields are set in relationship to each other. For example, if the X field is set to -1 and the Y and Z fields are set to 0, the fluid will flow parallel to the X axis in the negative X direction.
