Re: looking for package for convection-diffusion PDEs

<> >Hi,

Does anyone know of a fortran package to solve the >>convection-
diffusion PDE's
(maybe using the finite volume formulation)? I am >>looking to solve a
chemically reactive flow problem.

I saw Clawpack, but that one is for hyperbolic PDE's. >It >does offer

wondering how robust clawpack is for such problems.

Thank you,

Some questions concerning your request:

Do you want to model in 1d, 2d or 3d ?

2d-azimuthally symmetric

Is the flow convection- or diffusion-dominated ?

I think the flows are more diffusion dominated, but I >could have
borderline cases.

Thanks,

Hi,

in my opinion, for reacting flows with mild convection, CLAWPACK is not the best choice.

Better try KASKADE or KARDOS available at
