ReactionPDETerm

ReactionPDETerm[vars, a] represents a reaction term a u with reaction coefficient a and with model variables vars.

ReactionPDETerm[{u, {x1, …, xn}}, a, pars] uses model parameters pars.

Examples

Create a reaction term:

ReactionPDETerm[{u[t, x], {t, x}}, k]

Use in a PDE system:

eq = ReactionPDETerm[{c[t, x], {t, x}}, -k c[t, x]];
NDSolve[{eq == 0, c[0, x] == Exp[-x^2]}, c, {t, 0, 1}, {x, -5, 5}]
