Error in symmetry boundary condition

Hi

I am simulating a ventilated disc brake rotor in CFX. Only one-fourth of the disk brake has been computed because of the its symmetry.
But I have an the following error:

Why does this happen?

Some BC are as follows:

I am grateful that guide me in this case.

Thanks.

Exactly as the error message states, your boundary "sym solid" is on two planes at 90 degrees to each other. It needs to be a single plane. So split this symmetry boundary into two symmetry boundaries, with each being a single plane.
