Got a question about 'copy periodic blocking' and 'o-grid'
 

Hi, I'm just constructing the full passage grid for turbine nozzle part.

When I copied a single passage without O-grid using 'copy periodic blocking' function, it worked well.

After putting an O-grid around stators, however, if I use 'copy periodic blocking' function, it takes forever.

My computer is one of the best model nowadays and it's been taking a couple of days and it's not been done yet.

Is there any possible reason for this problem?

I tried 'block transform', but this seems not very helpful since all the associations seem to be done again.

Any suggestion or help will be appreciated. Thank you for reading..
