FSI is one of the most valuable tools combining an initial boundary condition and geometry for CFD simulation combinig stress analysis of an elastic structure.
upon executing the CFD simulation pressure and shear distribution are extracted on an elastic structure. This forces cause deformation to the structure therefore alternating the geometry and effect the distribution of Navier-Stokes dependent variables extracting updated pressure and shear distribution.
This process could be at “steady state” as found in a n elastic wing deformation or unsteady dynamic such as in the phenomena of flutter for example.
The usual way to solve such problems is diverse. Mostly solved by a segregated solver but generally could also be solved in a monolithic solver solving the full set of equation as one set of equation.
Join this CFD blogger in an ANSYS state of the art 2-part series of ANSYS How To videos demonstrates the setup and solution of a two-way transient coupled analysis.
- The first is of an oscillating plate, using ANSYS Mechanical, ANSYS Fluent, and System Coupling. Part 1 shows the setup of the three systems in ANSYS Workbench’s Project Schematic, and reviews the settings specific to a coupled analysis in ANSYS Mechanical and ANSYS Fluent. System Coupling in ANSYS Workbench provides tight integration of ANSYS Fluent and ANSYS Mechanical to allow the most complex Fluid-Structure Interaction phenomena to be simulated in a single environment.

- The second part demonstrates shows the setup of the System Coupling system, and the solution of the coupled analysis. System Coupling in ANSYS Workbench provides tight integration of ANSYS Fluent and ANSYS Mechanical to allow the most complex Fluid-Structure Interaction phenomena to be simulated in a single.
