Symmetry plane and slip wall

[SAM WANG]

Dear all,

I am now trying to convert an OpenFOAM case to Pyfr, but the conversion of some boundary conditions I am not quite sure.

In my knowledge, for symmetry plane, the normal velocity is zero and the normal gradient of other variables are zero as well. For slip wall, normal velocity is zero and no effect on parallel velocity as well as viscous force is zero.
I think they are the same.

So My question is how to interpret "symmetry" boundary conditions for curved planes or planar planes in Pyfr, can I directly convert "symmetry" with "slip wall" in Pyfr?

By the way, I do not find anything about temperature when dealing with compressible flow. How to make temperature visible or should I calculate by myself to get temperature variable?

Thank you for your time.

Regards,
Sam
