Quick Start

This section briefly describes how to get up and running using ALFE. See Installation for more detailed information such as system requirements and different ways of installing and using ALFE.

static void Main(string[] args)
{
    // Create a cantilever model with 200 * 200 pixel elements
    Model model2d = new Cantilever2D(ElementType.PixelElement, 200, 200).Model;

    // Create a finite element system
    FESystem sys0 = new FESystem(model2d, Solver.SimplicialLLT);

    // Initialize the system
    sys0.Initialize();

    // Solve
    sys0.Solve();

    // Print model information
    Console.Write(sys0.Model.ModelInfo());

    // Print matrix inforamtin
    Console.Write(sys0.MatrixInfo());

    // Print solving information
    Console.Write(sys0.SolvingInfo());

    // Print displacement
    Console.Write(sys0.DisplacementInfo());

    Console.ReadKey();
