what is the best way
 

I finished a conjugate CFD simulation using CFX. Now I want to use the thermal results (temperature) of solid to do a stress analysis. What is the best way to do it in Workbench or Ansys?

Thanks

Workbench is designed so data like this can be easily transferred between solvers. But either will be able to do it.

thanks. Can you give me some keywords so that I can search in workbench help? It looks like workbench needs a project start from CAD, then meshing, then solving. I don't know how I can import my data (mesh information and temperature) to setup a workbench project. Thanks again

Using workbench to join solvers is called coupling. A key aplication of it is fluid-structure interaction or FSI where an FEA solver is coupled to a CFD solver.

thanks again. but I guess I should clarify my problem.

I have a CFX result which includes both fluid domain result and solid domain result, and I can export only the solid result part to Ansys Multifield file (say file is named as solid_temp.cdb file) in CFX solver. I found that this solid_temp.cdb basically has everything (mesh, temperature etc) to do a thermal stress analysis. I already figured out a way to conduct a stress analysis with this cdb file in Ansys by manipulating the file and writing an Ansys script, but I am interested to know, how to DIRECTLY use this file in Ansys-workbench to do a stress analysis? I tried to find a way in workbench, but it always looks to me that I have to build CAD, then mesh, then setup in workbench so that I can do a structural analysis. But in my situation, I don't want to build a CAD/mesh etc, I just want to utilize solid mesh/temperature results from CFX and use them directly in workbench to generate a stress result. Can I do that? Where should I look for related information in Help?

thanks a lot

I'm not completely sure, but as far as I know, there is no way to do this in CFX but using .cdb files, which is not very elegant. I haven't tried ANSYS 13 though.
