Detailed Description

template<unsigned DIM>
class Electrodes< DIM >

A class for setting up the boundary conditions associated with electrodes. There are two modes: grounding the second electrode, in which case the first electrode has an input flux (Neumann boundary condition) of the specified magnitude, the extracellular potential is fixed on the second electrode; or not grounded, in which case the opposite electrode has an equal and opposite output flux.

This class assumes the given mesh is cuboid, and the electrodes are taken to be the specified opposite surfaces.

Note the class now includes a pointer to the mesh as a member variable, as this is required to archive (reconstruct) itself. Because boost is clever it will still only archive one copy of the mesh.

Member Function Documentation

template<unsigned DIM>

void Electrodes< DIM >::ComputeElectrodesAreasAndCheckEquality	(	unsigned	index,
		double	lowerValue,
		double	upperValue
	)			`[inline, private]`

Helper method to compute electrodes area and check they are equal. Throws if they are not.

Parameters:

	index	The value i when applying the electrodes to x_i=a and x_i=b (a<b)
	lowerValue	The value a when applying the electrodes to x_i=a and x_i=b (a<b) (should be the minimum value of x_i for the given mesh)
	upperValue	The value b when applying the electrodes to x_i=a and x_i=b (a<b) (should be the maximum value of x_i for the given mesh)

bool Electrodes< DIM >::SwitchOff ( double time ) [inline]

Whether it is time to switch off the electrodes yet. THIS ONLY RETURNS TRUE ONCE - the first appropriate time. After that the electrodes assume they have been switched off and therefore this returns false.

Parameters:

bool Electrodes< DIM >::SwitchOn ( double time ) [inline]

Whether it is time to switch on the electrodes yet. THIS ONLY RETURNS TRUE ONCE - the first appropriate time. After that the electrodes assume they have been switched on and therefore this returns false.

Parameters:

time

the current time
