Advanced FSI Simulation
 
Hi All, GMO from Flow-3D only allow one direction FSI simulation. Soid deformation/stress due to fluids pressure is not considered. so, anyone know how to export Flow-3D transient fluids pressure to Abaqus or Ansys for advance stress or displacement analysis.

something similar is done in

http://www.terrabyte.co.jp/Presentation_flap-gate.pdf

see the last slide. I am not sure what is the procedure..

MAB thanks for the presentation, but do you have details information on how to transfer the fluids pressure from Flow-3D to Abaqus/Ansys for details stress/deformation analysis?

To run abaqus or ansys simulation, you need the node pressure information from the FLOW-3D result. To extract the pressure information in FLOW-3D, you could output the pressure information at the nodes at "Analyze Tab" and "Neutral File Tab". You could have the detail info. in "the on-line FLOW-3D Manual - Exporting Neutral File Data".

Moon Thanks for the info, but seem like no easy way to incorporate both FEA and CFD solver like Ansys-CFX or Star-CD.

Yes, That is true. there is No EASE way. But If you try, you would know that is Not So complicated. There is the other way to use FLOW-3D Text output data. IF You would use your own program to export FLOW-3D data to FEM Solver, you could make it.
