Dear Mathematica users, I would like to NDSolve a 2D fluid PD-equation for the velocity vector, - its x and y scalar components u[x,y,t] and v[x,y,t], and I would like to specify specific boundary conditions. I can do this for the most simple cases like: u[0,y,t] == 0 and u[l,y,t] == 0 for some l, but how would I specify that a normal component should be zero on the line y == x Tan[a] for some angle a, Is this at all possible to specify, and would NDSolve solve it? I.e.: a = Pi/3 u[x, Tan[a] x, t] + v[x, Tan[a] x, t] == 0 Thank you for answering, Borut Levart
