3.4.2 Including Interaction With Surrounding Flow

If the fibers in your simulation strongly influence the flow of the surrounding fluid and need to be considered, you must select Interaction with FLUENT under Options in the Fiber Model dialog box (Figure  3.4.1). When iterating a solution with ANSYS FLUENT, the fiber model equations are solved alternating with ANSYS FLUENT's flow equations. Source terms are also computed to couple the fiber equations with the fluid flow equations. The calculation of the source terms is performed only during the course of an ANSYS FLUENT computation. See Section  2.6 for a description of the source terms.
