Why mesh size does not significantly affect the result in thermal analysis then structural analysis?

    • sulthan


      I did a Mesh independent test for thermal analysis of a Cooling system and found that there was no significant change in temperature for different mesh sizes. What is the reason for this?

      Thank you.

      Mesh convergence is done to understand how the size of your mesh affects the solution. You start from a course mesh, go on reducing the size until the mesh is fine enough to not cause any further changes in the result i.e convergence. This way we make sure that the results are independent of the mesh size. In your case it is possible that you started with a mesh size which is already fine enough to not cause any further changes in results.
