Hi all,

I'm relatively new to ICEM and am in need of some help. I'm attempting to block out a moderately complex part so that I can produce a replay script and run a parametric study on a range of geometries. The part is cyclically symmetric, so cut into thirds it looks like this:



I've been having decent success thus far getting the blocks/premesh to associate to the complex geometry/fillets:






I've been using block splits and a spline edge split on the upper edges to sculpt all this out. The issue I keep running into is that when I try to add nodes radially (so that I don't have these massive pizza-slice elements) everything explodes:

3 nodes


10 nodes



Here's a couple pics of my current blocking:






I've been trying a variety of approaches--I tried edge-splitting the edges that should be associated with the inner and outer radii to make them match up, which just caused more trouble. Associating the edges that I think should connect to the outer radius causes similar issues.

Any tips on how I can block this out? Am I approaching this in the wrong way entirely, or am I just missing something vital?


By the way, a lot of my strategy here is coming from Simon's elbow tutorial and this one, (which I think is by Far? http://www.youtube.com/watch?v=roZNUbhFVJ0)

Feel free to let me know if any more info is needed to tackle this problem.

Thanks,

Andy

Are you sure about the associations of the edges marked in the following picture?

It seems to me, those edges needs to be associated to the outer radius's edges or surfaces. The arrows seem to indicate, that right now, those edges are projected to the inner radius.

I've addressed that, actually; associating those edges to the outer surface pretty much immediately results in the pre-mesh skewing beyond recognition. I've managed to solve the issue, though--I just created another part out of that negative space that I was trying to fill, and called that the fluid. Meshed up beautifully.

Currently just trying to get FLUENT to export XY data in something other than SI units, which is apparently impossible -.-

Can you share this geometry on dropbox, I'm tempted to try this !
