Hi, I'm simulation about flow and heat on room on heating panel
so I design quater of room in 3D and set two plane to Symmetry

If you see that picture (plane away 5mm from room's surfce), can see blue cross. that cross is setted as the two plane of symmetry

Though there is heating inlet from imported coordinate inlet profile for z axis,
I never know why that terrible cross line is showing

As your sight, Can I accept that line as result? or is there any possibility to change mesh, boundary condition???

plz tell me about all of method having few possibility to modify
Thank you
