Which method of the following is more accurate while solving different modules in ANSYS and Why:
1- To link (Share) the modules by each other
2- To Export the data of first module then Import it to the second module using (Sharing) same geometry
I tried both methods on Thermal and structure modulus but o got different output (Distribution) on graph and a little difference in Max. Value of O/p. Transient thermal was the first and Transient Structure is the second module.

Moving this to Structural Mechanics category to get better response.

Thank you for your replay but would you mind telling me why the direct link (Moving to) structure gives the better response ? And for this better response should i share the (Engineering data, Geometry, Model, and Solution) or the (Engineering data, Geometry, and Solution) in to the second category "Module" ?

People with certain specializations monitor specific discussions and hence it would help to post in the related category to get their attention.
Coming to your question. Can you please post snapshots and explain?

I think you are asking about the difference between sending Thermal results to Structural by sharing the Model (mesh) as in the A-B system pair versus sending the Thermal results to Structural without sharing the Model (mesh), just the Geometry as in the C-D system pair.
Structural models often need a fine mesh to capture a stress concentrating geometric feature, while the same geometry in the Thermal model can have a coarse mesh and have good accuracy.
Assuming you create the mesh that is adequate for the Structural model, you will get good accuracy from either system pair method, but you can save some computational time using the C-D method because you can make a coarse Thermal mesh and a fine Structural mesh.

That means the best method to get more accurate results is to directly link modules together (Either with linking the Model or not depending on my geometry) "As in attached image; fig.1 and 2", And the Export/import of data "As in attached image; fig.3" didn't give accurate results even with same Mesh properties, Right?

I think Figure 2 and Figure 3 should give the same results so long as the mesh in C and E are the same and the mesh in D and F are the same and you export and import all the significant digits in the results.
Perhaps some ANSYS experts can comment since I almost never Export data.
