Hi! how we can solve nonlinear coefficient pde in complex geometry like a disk?
[CapitalOmega] = Disk[]; Subscript[[CapitalGamma], D] = DirichletCondition[u[x, y] == 0, True]; duval = NDSolve[{(u[x, y])*D[u[x, y], y] == E^-(x^2 + 10 y^2), Subscript[[CapitalGamma], D]}, u, {x, y} [Element] [CapitalOmega]]
I recieved this message: Nonlinear coefficients are not supported in this version of NDSolve
