Constructor Detail

FixedBoundaryGrid

public FixedBoundaryGrid(int sx,
                         int sy,
                         int sz,
                         int level,
                         double interiorValue,
                         double boundaryValue)

construct from size, initial value for all elements in the interior and initial value for all elements at the boundary.

Parameters:

sx - the dimension in X

sy - the dimension in Y

sz - the dimension in Z

level - the resolution level

interiorValue - the value to which all interior grid elements will be set

boundaryValue - the value to which all boundary grid elements will be set

Method Detail

newInstance
