Usage

From source file:reactor.semibatchreactor.Simulation.java

public static void main(String[] args) {
    double[] initialConditions = { 10, 0, 0, 0, 300 };
    double[] tempParameters = { 2500, 280, 2, 0.004, 75240, 300, -7.9076 * Math.pow(10, 7) };
    double[] odeParameters = { 0.2, 6.14, 0, 2.37989273, 8.94266 * Math.pow(10, 12), 803373.6 };
    SemiBatchReactor reactor = new SemiBatchReactor(initialConditions, tempParameters, odeParameters);
    FirstOrderIntegrator integrator = new DormandPrince853Integrator(0.1, 0.1, 0.001, 0.001);
    FirstOrderDifferentialEquations ode = reactor;

    integrator.addStepHandler(reactor.stepHandler);
    integrator.integrate(ode, 0.0, initialConditions, 10, initialConditions);
}
