Hello everyone
Im working on energy equation in a 2D domain using QUICK discretization scheme.
could you please help me how should I treat boundary nodes?
the B.C. is constant temperature at downside and zero flux (insulation) in other 3 sides. I attached a schematic picture about my problem. I dont know how to treat the orange colored cells in that picture.
thank u in advance.

Leonard showed the BCs in his paper on

COMPUTER METHODS IN APPLIED MECHANICS AND ENGINEERING 19 (1979) 59-98



you just think about a second degree polynomial with a prescribed derivative at the boundary.
