How to make symmetry line BC in CFX that is on the line on which two symmetry palnes meet

Re: Symmetry BC
 

Hi,

If you define 2 symmetry planes, the line where they meet is automaticly a symmetry line.

In a symmetry plane, the velocity and gradients vectors normal to the plane are zero. So, at the line where 2 symmetry planes meet, the velocity and gradients vectors are zero in any direction normal to that line, which makes it a symmetry line, and you don´t need to define it as so.

Regards,

There is no need to do this in CFX-5. The flow solver will figure out that the two planes intersect at an axis and do the right thing.
