Flow visualization at overset mesh interface

haizhou0410 · December 22, 2020, 22:04

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 what can I do with this? Thank you very much in advance!

I could not find your error. I'm going to study again.

You have a nice flow field plot. I can't see any error that appeared in my case. How did you make this happen? Have you tried to plot this in tecplot? Thank you! Btw, nice model.

have you looked at the equivalent scenes in star using its post processing which is designed to automatically deal with the display of overset mesh results?

if they look correct then why go to tecplot anyway- what does it have that star can't do for general p.p.?
