create block by rotaon problem

ztdep · December 27, 2015, 04:10

Dear friends:
I create a 3D cylinder type object by rotation 2d multibock grid with 360 degree.
But i noticed the 2D grid was specified as a wall after import into the fluent 15.
So could you please give me some suggestions how to treat it like a interior grid

Check to ensure that there is only one 2D domain (as opposed to one at the 0 degree position and a 2nd coincident one at the 360 degree position).

Use the Set BCs command to verify that the 2D domain is set as an interblock connection. Because there are some flow solvers that do not allow a block to connect to itself, you may have to split your cylinder into two 180 degree portions.

Over-ride the boundary condition in Fluent.
