ICEM CFD Introductory Course Geometry

•  Set adequate tolerance!

–Example: some multiple (blue) edges.  This indicates that more then two surfaces meet within the tolerance setting

–Turning on the surfaces reveals one surface is now missing.

–In this case, the tolerance was set to greater than the thickness, one of the surfaces was seen as a “duplicate” within the tolerance and removed.   UNDO

–You will need to exercise care not to damage your model with build topology

–Rule of thumb:  tolerance should be about 1/10th smallest foreseen mesh size or smallest feature that you wish to capture

–Build topology with delete duplicate geometry because its tolerance is zero
