hm... u think this way because maple say:

MY PDE

pde := (diff(H0(T(z, r, t)), T))*(diff(T(z, r, t), t)) = (diff(r*lambda0(T(z, r, t))*(diff(T(z, r, t), r)), r))/r+diff(lambda0(T(z, r, t))*(diff(T(z, r, t), t)), z)+Q

ERROR

Error, (in pdsolve/numeric/process_PDEs) can only numerically solve PDE with two independent variables, got {r, t, z}

 

and i see some comments in internet that maple can solve only 2 variables pde.

this is very bad =(

that's why...
