Mixed cell zone remeshing in FLUENT 12
I can read this from the User's Guide :
The available remeshing methods in ANSYS FLUENT work for triangulartetrahedral
zones and mixed zones where the non-triangular/tetrahedral elements are
It doesn't seems to work for me. I have two zones :
1/ Hexahedral zone (sweep mesh);
2/ Mixed cell zone (tetrahedral conforming mesh);
So in the mixed cell zone I have pyramids that make transition from HEX to TET elements. The issue is that when the interface between the two zones is moving (compressing the mixed cell zone) I have negative volumes appearing.
I know that I can make wedges instead of hex, make hex with non-conformal interface, make a transition layer with pyramids only etc.. But I want to know why it doesn't work like it is written in the manual.:confused:
Thanks in advance.
