turbine flow volume decomposition

Hi,
I have been working on generating some turbine geometry in Gambit which is part of a larger batch automated routine, and therefore have used vertex input files for the blade / volume geometry and a gambit journal to create the model ... My problem is, based on tests, it seems i need to use a hex mesh to capture the flow dynamics correctly, and so need to decompose the flow volume. was wondering if anyone had any ideas of the best way to try to decompose the volume i.e. o / c / h grids as i have tried a heap of methods but dont seem to be able to get a decent mesh! part of the problem seems to be that the blade is highly twisted and coopering from hub to tip ends up with a heap of inverted cells ... any ideas the best way to decompose the volume?? thanks a lot!! ps attached are a couple screen shots of the geometry at the moment... |
