Need help for Gambit/Fluent/ANSYS data transfering

S-Y. Chen

I am not quite familiar with Fluent but I am working with my colleage to transfe data between ANSYS and Fluent. We are doing conjugated heat transfer of a system with fluid and solid. It will be greatly appreciated if any of you can give me some help

My question is

1. I read in the ANSYS CDB file (which consists of the mesh of the solid) from Gambit. But then only the "surface" of the solid mesh is imported. Why ? How can I make Gambit to read the whole solid instead of just the surface ?

2. I have calculated the heat generation rate in each of the solid element. But, how can I apply them to each mesh in Gambit ? In my ANSYS CDB file there are heat genertation rate as body force. But it seems Fluent can not recognize or import them. Is there any convenient way to transfer the heat generation rate from ANSYS into Fluent/Gambit ? (I need to apply it element-by-element or cell-by-cell, not through surface or volume)

3. I have seen someone mentioned the "PATCH" command in this group. But because I am not very familiar with Fluent, I can not find this command in the manual. Can anyone guide me ?

4. I am considering using the NEUTRAL FILE to transfer the BC from ANSYS to Fluent. But is there any similar approach to transfer result data from Fluent to ANSYS using the text file ? Can Fluent write the result plus the mesh in the ANSYS format ?

Thanks for your help
