How to create interface between periodic model and full model?

shivasluzz · September 13, 2015, 13:16

I have two domains..
One is axisymmetric and so I made only 30 deg of it
Another is not axisymmetric and so I made full model..
Now what is the method to connect these 2?

Use a GGI. If you want the 30 slice to connect to the full thing as if it were the full 360 degrees then use a pitch ratio with a rotating frames of reference. If your domain does not rotate then fool it by setting the rotational speed to almost zero.

Ya my domains doesn't rotate and your idea of fooling it with near zero speed is good

thanks ghorrocks and sorry for the late reply
