Import mesh from GAMBIT to Mechanical

      Hi everyone,


      I'm doing FSI simulation in ANSYS 17.2, and meshed both the solid and the fluid domain in GAMBIT 2.4.6. I have no problem in importing the fluid mesh in Fluent, while to import in Mechanical it's a bit tricky. I export the mesh from GAMBIT, then import it in the External Model component system and share with the Transient Structural system. My questions are:


      - Can this tricky process compromize the simulation, like causing a mismatch at the fluid-solid interface?


      - Is there any way to import a mesh directly from GAMBIT to the Transient Structural block?


      Thank you for your help!

      Given GAMBIT hasn't been developed in about 10 years and R17 is 3 years out of date I'd suggest updating to 2019R2 when you can. 


      If the mesh is transferred then there shouldn't be a mismatch. If you're remeshing that's likely to not match.  How are you controlling the FSI data transfer?

      Thank you for your answer rwoolhou,


      I am doing remeshing at each iteration. Data transfer are force (under relax factor 0.3) and incremental displacement. Is that what you meant by controlling the FSI data transfer?

      Not quite: what transfers the data from Mechancial back to Fluent?

      I guess is the System Coupling that tranfers data. Anyway I tried to run the simulation and it seems to work with no problem.
