I have a structural problem that I want to run which involves a beam that is deflected by stresses unrelated
to fluid forces. To get this deflection, I am going to solve a steady-state structural problem in ANSYS.
I would then like to do a standalone CFD simulation for flow around the beam.
What is the best way to get the mesh for the deformed beam into the
With an MFX license, you can set this up as a 2-way FSI problem.
Set up your ANSYS structural analysis as usual. Just remember to put
a Fluid-Solid interface on the solid surface that meets the fluid. You can go ahead
and run and save your analysis.
In CFX, you can set up a transient simulation with external coupling to ANSYS. You will specify that
CFX will receive Total Mesh Displacement from ANSYS but will pass it back nothing.
You need only run a timestep or two.
Under Solver Control, you will specify for ANSYS to solve first.
Once it`s all set up, run the problem. The deformed mesh will be present in the CFX results file. You can import the
mesh from this results file into a new session of CFX-Pre so that the deformed mesh will now be available for a new
