Answer:
Yes, the results can be partially exported. The export function is available for the result tables in the add-on module (as of Window 2.1).
Using the example of the steel stress in SLS, it would be possible to only perform the steel stress analysis and then export the table in Window 3.3, for example.
When displaying the table in Window 3.3, you can choose between FE mesh points and grid points. The grid can be adjusted as a property of the surface.
