====== ODE ====== An ordinary differential equation (or ODE) is a relation that contains functions of only one independent variable, and one or more of its derivatives with respect to that variable. An independent variable in Ecolego is represented by a [[Compartment|compartment]] block. When running a simulation, a system of ODEs are set up and solved by a numerical solver. ===== See also ===== * [[ODE_solver_reference|ODE solver reference]]
