Turbine blade with filleting and tip clearance

Posted February 10, 2013 at 22:06 by diamondx

The periodicity (set under Mesh (tab) => Global Parameters) is to ensure that your mesh on one side matches the mesh on the other side... Once you see the DEZ (data entry zone), you will understand what you need to fill in. Periodicity is set on the geometry so that the generated mesh comes out periodic, so if you go back to set it, you must regenerate.

Even if you are copying your mesh around to create an annulus instead of a periodic section, it will be easier if you have...

Options... by simon

The ICEM CFD Prism algorithm can not move hexa's out of the way as it inflates the prisms. Therefore, you need to make sure that you don't convert tetra to hexa before prism inflation.

With ICEM CFD, there are always other ways...

1) You could try a Hexa (blocking tab) mesh. This would be really easy if you really wanted to do a sphere in a box... What is your real application? Aircraft shapes, wings, etc. are also pretty easy to do with Hexa blocking. It gives...

TUI commands for animating air/water interface

Posted January 26, 2013 at 16:00 by diamondx

Good to know from zippyhybrid

I create similar animations however since I am investigating air-lift driven flow and am interested in the behavior of bubbles in the airlift column. I'd suggest visualizing the interface using contours of phase

Exporting blocking/mesh for a similar geometry By simon

Posted January 6, 2013 at 19:23 by diamondx

During import, you can also associate the new geometry file with the old tetin file so all the family sizes, etc. are preserved... This is an option near the top of the import DEZ.

Then load the old blocking file and update the associations.

If they don't all auto associate properly, you can use the interactive controls to adjust things...
