Wow Rob, once again a very telling reply from you!
That's what I guessed, I have colleagues working with external flows who were hardly aware of the matter.
But it's good to know that it's OK to ask for (and work with) more substantiated input data when compressibility comes in the picture.
I will hopefully manage to check out some theory about that, for the moment I'm just happy I did not bring up a non-issue.
Thank you again Rob, always relieved when you come to help!!
