Question about boundary condition of 2D Burgers equationHello?
I would like to ask boundary condition of 2D Burgers equation. I consider following equation. U_{t} + ( (1/2)U^2 )_{x} + ( (1/2)U^2 )_{y} = 0 with the Riemann initial value U(x,y,0)= 2.0 (x<0), 1.0 (x>0) I guess that left and right boundary value is 2.0, 1.0 respectively. But what is the top and bottom boundary condition? |
