/**
 * Runs the simulation./*from  www . j a  va  2s .  c  om*/
 */
public void runSimulation() {

    // stop previous running simulation
    // does nothing if no simulation is running
    stopSimulation();

    // state vector
    int numBodies = particles.size();
    double[] y = new double[numBodies * ODEParticle.getStructSize()];
    double[] m = new double[numBodies];
    boolean[] ignoreFlags = new boolean[numBodies];

    // ui nodes
    nodes = new Node[numBodies];
    rotations = new Rotate[numBodies];

    // gravitational constant
    // see https://en.wikipedia.org/wiki/Gravitational_constant
    double G = 6.672e-11 * 0.000000001; // scaled G

    // initialize particles
    for (int i = 0; i < numBodies; i++) {
        Particle p = particles.get(i);
        p.apply(i, y, m);
        nodes[i] = p.toJFXNode();
        rotations[i] = new Rotate(0, new Point3D(0, 1, 0));
        nodes[i].getTransforms().add(rotations[i]);
    }

    // setup ODE system
    FirstOrderDifferentialEquations odeEqSys = createODE(numBodies, y, m, ignoreFlags, G);

    // start frame listener
    initFrameListener(odeEqSys, y, m, ignoreFlags, 0.001);
