Dear Peers,

I am simulating a CHT problem, in which there is a rectangular Duct with a hot object placed inside for cooling. The cool air is injected from two side circular nozzles. There is an outlet at bottom, where I Specified Pressure outflow boundary condition. The faces in X and Y directions are walls. The two Faces on either sides of duct (in Z-direction), are open and I wanted to specify Symmetric boundary condition.

SIDE1
{
type symmetryPlane;
}

While launching the CHT case, this boundary condition is not recognised and solver aborts.

Any suggestions would be helpful
Thank you
