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?


a = Pi/3
u[x, Tan[a] x, t] + v[x, Tan[a] x, t] == 0

Thank you for answering,
Borut Levart
