Class Grid2D

  • All Implemented Interfaces:
    Serializable, Descriptive
    public class Grid2D
extends Grid

    A Grid2D is used to partition the space and time domain of a Problem2D to allow a numeric solution with a DifferenceScheme. This type of grid is two-dimensional in space, meaning that it defines rules for partitioning of both the axial and radial dimensions for interpreting the laser flash experiments.

      • Grid2D

        public Grid2D​(NumericProperty gridDensity,
              NumericProperty timeFactor)
        Creates a Grid2D where the radial and axial spatial steps are equal to the inverse gridDensity. Otherwise, calls the superclass constructor.
        Parameters:
        gridDensity - the grid density
        timeFactor - the &tau;<sub>F</sub> factor

      • copy

        public Grid2D copy()
        Description copied from class: Grid
        Creates a new Grid object with exactly the same parameters as this one.
        Overrides:
        copy in class Grid
        Returns:
        a new Grid object replicating this Grid

      • setTimeFactor

        public void setTimeFactor​(NumericProperty timeFactor)
        Description copied from class: Grid
        Sets the value of the tauFactor. Automatically recalculates the tau value.
        Overrides:
        setTimeFactor in class Grid
        Parameters:
        timeFactor - a NumericProperty of the TAU_FACTOR type

      • adjustStepSize

        public void adjustStepSize​(DiscretePulse pulse)
        Calls the adjustTo method from superclass, then adjusts the gridDensity of the grid if discretePulseSpot < (Grid2D)grid.hy.
        Parameters:
        pulse - the discrete puls representation

      • setGridDensityValue

        Sets the value of the gridDensity. Automatically recalculates the hx an hy values.
        Overrides:
        setGridDensity in class Grid
        Parameters:
        gridDensity - a NumericProperty of the GRID_DENSITY type

        public double gridRadialDistance​(double radial,
                                 double lengthFactor)
        The dimensionless radial distance on this Grid2D, which is the radial/lengthFactor rounded up to a factor of the coordinate step hy.
        Parameters:
        radial - the distance along the radial direction
        lengthFactor - a factor which has the dimension of length
        Returns:
        a double representing the radial distance on the finite grid
