Thanks for the answer. I considered that as an option but my model is a bit more complicated as the described two tubes (just used it as an example) and thus, I did not want to redesign the whole thin again.

I used a different software to make the model and named the desired parameters with DS_, but if I use fluent meshing I can never define these parameters as inputs and they don't show up in SpaceClaim either. (It works for mechanical of course).
