How to solve a pde with three or more variables in pytohn? For example:
f = Function('f')
u = f(x, y, z)
ux = u.diff(x)
uy = u.diff(y)
uz = u.diff(z)
eq = Eq(y*ux-(x+z)*uy + y*uz, 0)
pdsolve(eq)
But i got the error:
NotImplementedError Traceback (most recent call last) in 5 uz = u.diff(z) 6 eq = Eq(y*ux-(x+z)uy + yuz, 0) ----> 7 pdsolve(eq)
