visual glitches
 

Hi Im running hex mesh i created in pro*am and im having problems with the visualisation. The mesh looks fine but when i post-process i have little glitches. I am analysing external flow and these glitches look like little bits of cell sticking out from the tool i am studying. i have recently started using 3.15 and i never had this problem on 3.100 indeed meshes i ran before in 3.100 are now doing the same thing in 3.15, is this a software bug or a problem with my mesh. many thanks Joel
