[ICEM] Eliminating Negative Volume Elements -- CFD Online Discussion Forums

April 14, 2010, 18:15	Eliminating Negative Volume Elements	#1
Josh Senior Member Joshua Counsil Join Date: Jul 2009 Location: Halifax, Nova Scotia, Canada Posts: 366 Rep Power: 17	Hello all - Despite that I have used minimal smoothing in ICEM (I just smoothed for orthogonality, being that it is a hexahedral grid), my grid appears to have negative volume elements, as shown below. Apparently, as shown on the left in blue writing and in the histogram, there are almost 63 negative volume elements (8 + 55), with the smallest being -18.7586 mm^3. I need to get rid of these, but am not sure how. Any ideas?
