Hi everyone,

I use star-ccm+ overset mesh method to do flow simulations with motions. I found that the flow e.g. vorticity plot at the overset mesh interface has some problems. It seems that not all unwanted cells are blanked. I use tecplot value blanking and use the "blank entire cells when 'primary value is blanked' "option and blanked the cells when overset cell status equal to 1, -1, -2 which corresponding to inactive, acceptor that is used as donor and acceptor respectively. But it still has problems with the interface which are shown in the picture. Does anyone know how to deal with this? Thank you very much in advance!
