I am trying to solve a PDE of the form
pde:=diff(X(b,h),h,h)+2*diff(X(b,h),h)+(b^2)*(X(b,h))=diff(G(b,h),h)+G(b,h)
The pdsolve(pde,X) command gives me an equation of the form
X(b,h)= ()_F1+ ()_F2+()
the boundary conditions are
X(b,0)=0
and (diff(X(b,h),h)@h=0)=0
how do I solve this PDE and evaluate the _F1 and _F2 terms.
Thanks,

Clearly you have to specify G to get computable integrals (they may or
may not give a closed form). Then you have to fit the result to the
boundary conditions you must specify as a function of b. You might
try integrating the integrals in G by parts to see if they simplify at
all.
