This is a demo on how to implement a chute flow with a rough bottom. Note that this is the same code as roughBottomSelfTest, but with a bigger chute, a larger gravity and a longer simulation time. [RB:main]

{
    //Print description
    logger(INFO, "\nDemo of the chute flow with a rough bottom");
    
    //Construct the problem and assign a name
    Chute roughBottomSelfTest;
    roughBottomSelfTest.setName("roughBottomMultiLayer");
 
 
    //Set time stepping parameters
    roughBottomSelfTest.setTimeStep(1e-4);
    roughBottomSelfTest.setTimeMax(0.1);
 
    //Set output parameter: write to the output files every 50 time steps
    roughBottomSelfTest.setSaveCount(50);
 
    //Set the particle radii and the type of the rough bottom
    roughBottomSelfTest.setInflowParticleRadius(0.5);
    roughBottomSelfTest.setFixedParticleRadius(0.5);
    roughBottomSelfTest.setRoughBottomType(MULTILAYER);
 
    //Set the particle properties
    LinearViscoelasticSpecies* species = roughBottomSelfTest.speciesHandler.copyAndAddObject(LinearViscoelasticSpecies());
    species->setDensity(6.0/constants::pi);
    species->setStiffness(2e5);
    species->setDissipation(25.0);
 
    //Set the chute properties
    roughBottomSelfTest.setChuteAngleAndMagnitudeOfGravity(24.0, 1.0);
    roughBottomSelfTest.setChuteLength(3.0);
    roughBottomSelfTest.setChuteWidth(3.0);
 
    //Solve the system
    roughBottomSelfTest.solve();
