Hej,
i'm quite new to maple and i want your advice /guidance(in fact i'm desperate)

in order to solve a system of 2 pdes coupled with 4 odes.
the pdes are :

diff((r1(t)*C1(t)+r2(t)*C2(t))*T(z,t),t)=diff(k(T(z,t))*diff(T(z,t),z),z)+Q*r1(t)

diff(e(t)*Y(z,t),t)=diff(D(Y(z,t))*diff(Y(z,t),z),z)-(B*exp(T(z,t))*r1(t)

odes:
diff(r1(t),t)=-(A*exp(T(z,t))+B*exp(T(z,t)))*r1(t)

diff(r2(t),t)=A*exp(T(z,t)*r1(t)

diff(r3(t),t)=B*exp(T(z,t)*r1(t)
