Symmetry problem
 

Hey,

my problem is the partial symmetry of my geometry.

The whole geometry consists of a non-symmetric pipe with air and inside this pipe there is a symmetric body.

My question:
Is it possible to create only one half of the body and to give the symmetry plane of the body the boundary condition "symmetry"? Or is the b.c. "symmetry" only available for the whole geometry?

Thank you in advance for your answers!

That is a solver question... Ask it in the forum of your particular solver.
