— Class: <CDRSYS-PROBLEM>

Problem class for a system of convection-diffusion-reaction equations.

Superclasses: <ELLSYS-PROBLEM>

— Function: CDRSYS-MODEL-PROBLEM DOMAIN NCOMPS &KEY (DIFFUSION NIL DIFFUSION-P) (SOURCE NIL SOURCE-P) (DIRICHLET NIL DIRICHLET-P) CONVECTION REACTION INITIAL EVP PROPERTIES

Generates a system of convection-diffusion-reaction equations. Defaults are identity diffusion, right-hand-side equal 1, and Dirichlet zero boundary conditions for each component. Ordinary function are converted into coefficient functions depending on a global coordinate. The first argument can be either a domain or an integer n which is interpreted as the n-dimensional unit cube.
