ITI - CADfix

Mark and I discuss why CAD is still a problem for CFD and introduce you to the saviour of your blocking structure, the medial object.

Today we’re talking about an integral part of most CFD processes that often gets ignored. It comes before we start our CFD process, yet often has a huge impact on that process – CAD.

I’m chatting with Mark Gammon, Technical Director of the Cambridge office of ITI & one of the team behind their software package CADfix (the clue is in the name). Mark has an in-depth knowledge of CAD that many of us CFD people don’t – he fills me in on:

  • what makes CAD so tricky to work with in CFD & why solid modelling isn’t really;
  • what on earth a medial object is & why it could be hugely important for CFD meshing;
  • why going back-to-CAD is still such a tricky problem;
  • what sort of pre-meshing / CAD-cleanup jobs we’ll soon be able to automate & whether we’re about to lose the human from the CFD meshing loop altogether.
