Class IterativeSolver

  • All Implemented Interfaces:
    Serializable, Descriptive, Reflexive
    Direct Known Subclasses:
    FixedIterations, SuccessiveOverrelaxation
    public abstract class IterativeSolver
extends PropertyHolder
implements Reflexive
    Used to iteratively solve the radiative transfer problem.

    This is necessary since the latter can only be solved separately for rays travelling in the positive or negative hemispheres. The problem lies in the fact that the intensities of incoming and outward rays are coupled. The only way to solve the coupled set of two Cauchy problems is iterative in nature.

    This abstract class only defines the basic functionaly, its implementation is defined by the subclasses.

      • IterativeSolver

        public IterativeSolver()
        Constructs an IterativeSolver with the default thresholds for iteration error and number of iterations.

      • doIterations

        public abstract RTECalculationStatus doIterations​(AdaptiveIntegrator integrator)
        De-facto solves the radiative transfer problem iteratively.
        Parameters:
        integrator - the integerator embedded in the iterative approach
        Returns:
        a calculation status

      • getIterationErrorTolerance

        public NumericProperty getIterationErrorTolerance()

      • setIterationErrorTolerance

        public void setIterationErrorTolerance​(NumericProperty e)

      • set

        public void set​(NumericPropertyKeyword type,
                NumericProperty property)
        Description copied from class: Accessible

        An abstract method, which must be overriden to gain access over setting the values of all relevant (selected by the programmer) NumericProperties in subclasses of Accessible. Typically this involves a switch statement that goes through the different options for the type and invokes different set(...) methods to update the matching NumericProperty with property.

        Specified by:
        set in class Accessible
        Parameters:
        type - the type, which must be equal by definition to property.getType().
        property - the property, which contains new information.

      • listedKeywords

        public Set<NumericPropertyKeyword> listedKeywords()
        Description copied from class: PropertyHolder

        By default, this will search the children of this PropertyHolder to collect the types of their listed numeric parameters recursively.

        Overrides:
        listedKeywords in class PropertyHolder
        Returns:
        a set of NumericPropertyKeyword instances, which have been explicitly marked as a listed parameter for this PropertyHolder.

      • setMaxIterations

        public void setMaxIterations​(NumericProperty iterations)

      • getIterationError

        public double getIterationError()
