Negative volume in ICEM CFD
I am trying to hex-mesh my geometry in ICEM-CFD. I am getting some negative volume elements as can be seen in the link. The elements shown in the link are the only negative volume elements. http://ez-files.net/download2.php?a=...9bb952c19dfa0f
The geometry consists of a cylinder having three baloon shaped surfaces on the curved surface of the cylinder as seen. The screenshot in the link shows the region of the cylinder where the ballon shaped surfaces lie.
The negative volumes come up the moment I collapse certain blocks to get the blocks as seen.
What could be the cause of the same?
Any help or queries are appreciated.
