Fluent solves a simple steady fluid flow problem, where the flow is affected by the momentum sources defined in the SCDT file. **Problem description** Fluid flow problem consists of the water flowing through the pipe. .. image:: /_static/fluid_swirl_setup.png :width: 400pt :align: center The SCDT file will be generated that consists of a cloud of points overlapping the fluid domain. At each point, the force density value is defined, with force acting along the flow cross-section, always in a counter-clockwise direction (if looking from the inlet to the outlet). System Coupling is used to map the data from the cloud of points defined in the SCDT file onto Fluent mesh. The force values are then transferred into Fluent and Fluent solves the resulting fluid flow problem, where the fluid is influenced by the provided forces. As a result, the swirl is induced in the fluid flow. .. GENERATED FROM PYTHON SOURCE LINES 53-56 .. code-block:: Python # Tags: SCDT, Fluent, steady ..
