Method Detail

getGrid

public Grid getGrid()

Returns the grid on which the equation was defined.

Returns:

A Grid object.

getCoordinates

public java.util.List<java.lang.String> getCoordinates()

Returns the list of coordinates in the correct order.

Returns:

The names of the coordinates.

getStationaryFields

public java.util.List<java.lang.String> getStationaryFields()

getConstant

public double getConstant(java.lang.String constantName)

Returns the value of the given constant. TODO what happens if the constant is not defined?

Parameters:

constantName - the name of the constant

Returns:

the value of the constant.

getBoundaryConditions

public jabble.BoundaryConditions getBoundaryConditions()

Returns the boundary conditions that are defined with the equation set.
