Getting better worst element in ICEMCFD

henda_ananta · May 28, 2011, 05:53

Hi, guys. i'm new on ICEMCFD. i have a question about worst element in ICEMCFD. i have meshed my geometry for many times and got my best worst tetra about 0.46. i have heard that worst element that closer to 1 will give more accurate result in predicting. so, how are the way to get the worst element closer to 1?

Best regards,
Henda

ICEM has lots of mesh manipulation methods, get familiar with them and you will figure it out. You can smooth (with dozens of different algorithms), manually move, split, merge, convert to a different element type, make small geometric changes and lots more - but to work out which one to use to improve your mesh, that is the big question. That is why they employ people as CFD specialists.
