fluid/structure interaction(FLUENT/LS-DYNA) help!!
 
i'm working on a project that deals with fluid structure interaction. the project is to model a volume in GAMBIT and mesh it, export it to FLUENT to simulate a flow on the structure and analyze it, export the pressure loads on the structure to LS-DYNA for deformation simulation and re-import deformed mesh and volume for fluid analysis. so its basically a coupling between programs to do fluid structure interaction(FSI). the problem is i'm working with another student who uses LS-DYNA and i'm using GAMBIT/FLUENT. does anyone have any straight forward procedure to transfer pressure grid from FLUENT to LS-DYNA and then re import deformed mesh from LS-DYNA to fluent??? if you anyone did this simulation before, can you tell me how u did it by a simple example such as a simple solid cube under deformation. thanks

You need a coupler between your CFD and FE programs. It may be that Fluent does not work with LS-DYNA. I think Fluent works with ABAQUS though. You will need a special license from Abaqus and possibly Fluent. Go here and find out more info, its a big undertaken if you have never done it before:http://www.scai.fraunhofer.de/mpcci.html
