double CryptProjectionForce::CalculateCryptSurfaceDerivativeAtPoint ( const c_vector< double, 2 > & rNodeLocation )

Calculates the derivative df/dr of the crypt surface function z=f(r) at a point whose 2D position is a distance r from the centre of the cell_population, which we assume to be at (0,0).

Parameters:

rNodeLocation the 2D location of a node

Returns:: the gradient

double CryptProjectionForce::CalculateCryptSurfaceHeightAtPoint ( const c_vector< double, 2 > & rNodeLocation )

Calculates the height of the crypt surface given by z = f(r) = a*r^b at a point whose 2D position is a distance r from the centre of the cell population. This assumes that the cell population is centred at the origin.

Parameters:

rNodeLocation

Returns:: the z component corresponding to rNodeLocation
