[R-sig-dyn-mod] Desolve on PDEs

[Karline Soetaert]

They look like partial differential equations to me. You could have a look at the R-package ReacTran that solves PDEs (and which uses deSolve) . You would need to use ode.1D and tran.1D

Hope it helps, Karline

Subject: [R-sig-dyn-mod] Desolve on PDEs

 Hello,
I would like to know if deSolve is the right R package to solve the following partial derivative equations:
-jP1/jX * c1 +jP1/jT = -u1P1 + u2P2 jP2/jX * c2 +jP2/jT =  u1P1  - u2P2 where c1,c2,u1, and u2 are constants. Initial values are known (i.e P1(X=0,t)=0 and P2(X=B,0)=0 where B is a given number).
I saw a few examples, but they seem to be even more complex than what I would like to achieve (i.e. 2nd order PDE). What the sketch of a model could be? And which function would be appropriate (0de.1D)?
Thanks,
Enrico
