Member Function Documentation

bool CryptStatistics::CellIsInSection ( double  xBottom,
double  xTop,
double  yTop,
const c_vector< double, 2 > &  rCellPosition,
double  widthOfSection = 0.5 
) [private]

Method computing the perpendicular distance from the cell to the line from (xBottom, 0) to (xTop, yTop), and returning if the distance is within the specified width to the section (defaults to 0.5).

Parameters:
xBottom the x coordinate of the bottom of the line
xTop the x coordinate of the top of the line
yTop the y coordinate of the top of the line
rCellPosition the location of the cell centre
widthOfSection the width of the line
Returns:
whether the cell is in the section

bool CryptStatistics::CellIsInSectionPeriodic ( double  xBottom,
double  xTop,
double  yTop,
const c_vector< double, 2 > &  rCellPosition,
double  widthOfSection = 1.0 
) [private]

Method computing the perpendicular distance from the cell to the line from (xBottom, 0) to (xTop, yTop), taking into account periodicity, and returning if the distance is within the specified width to the section (defaults to 1.0). Done by considering the two possible lines and checking if cells are within range.

Parameters:
xBottom the x coordinate of the bottom of the line
xTop the x coordinate of the top of the line
yTop the y coordinate of the top of the line
rCellPosition the location of the cell centre
widthOfSection the width of the line
Returns:
whether the cell is in the section

std::vector< CellPtr > CryptStatistics::GetCryptSection ( double  yTop,
double  xBottom = DBL_MAX,
double  xTop = DBL_MAX,
bool  periodic = false 
)

Get all cells within a cell width of the section defined as the line between points (xBottom,0) and (xTop,yTop)

Periodicity can be taken into account (if xTop and xBottom are more than half a crypt width apart then a more realistic section will be across the periodic boundary), using the final parameter. This obviously requires the mesh to be cylindrical.

Parameters:
yTop the y coordinate of the top of the line
xBottom the x coordinate of the bottom of the line (defaults to a random number U[0,crypt_width])
xTop the x coordinate of the top of the line (defaults to a random number U[0,crypt_width])
periodic whether periodicity is accounted for (defaults to false)
Returns:
an ordered list of CellPtrs from the bottom to the top of the crypt.

Note that placing calls to functions with side-effects (eg. changing the random seed) in the default arguments is DANGEROUS. There is no guarantee that the compiler will execute these in a sensible order. It appears that Intel goes left-to-right and Gcc goes right-to-left.

std::vector< CellPtr > CryptStatistics::GetCryptSectionPeriodic ( double  yTop,
double  xBottom = DBL_MAX,
double  xTop = DBL_MAX 
)

Get all cells with a cell width of the line defined by the points (xBottom,0) and (xTop,yTop), taking into account periodicity

If xTop and xBottom are more than half a crypt width apart then a more realistic section will be across the periodic boundary.

Note that placing calls to functions with side-effects (eg. changing the random seed) in the default arguments is DANGEROUS. There is no guarantee that the compiler will execute these in a sensible order. It appears that Intel goes left-to-right and Gcc goes right-to-left.

Parameters:
yTop the y coordinate of the top of the line
xBottom the x coordinate of the bottom of the line (defaults to a random number U[0,crypt_width])
xTop the x coordinate of the top of the line (defaults to a random number U[0,crypt_width])
Returns:
an ordered list of CellPtrs from the bottom to the top of the crypt.
