Detailed Description

class AbstractCardiacMechanicsSolver< DIM >

AbstractCardiacMechanicsSolver

Base class to implicit and explicit cardiac mechanics solvers. Inherits from NonlinearElasticitySolver Main method is the overloaded AssembleOnElement which does the extra work needed for cardiac problems. The child classes hold the contraction models and need to implement a method for getting the active tension from the model.

Pure method called in AbstractCardiacMechanicsSolver::ComputeStressAndStressDerivative(), which needs to provide the active tension (and other info if implicit (if the contraction model depends on stretch or stretch rate)) at a particular quadrature point. Takes in the current fibre stretch.

void AbstractCardiacMechanicsSolver< DIM >::SetConstantFibreSheetDirections ( const c_matrix< double, DIM, DIM > & rFibreSheetMatrix ) [inline]

Set a constant fibre-sheet-normal direction (a matrix) to something other than the default (fibres in X-direction, sheet in the XY plane)

Parameters:

rFibreSheetMatrix

The fibre-sheet-normal matrix (fibre dir the first column, normal-to-fibre-in sheet in second column, sheet-normal in third column).

void AbstractCardiacMechanicsSolver< DIM >::SetVariableFibreSheetDirections	(	std::string	orthoFile,
		bool	definedPerQuadraturePoint
	)			`[inline]`

Set a variable fibre-sheet-normal direction (matrices), from file. If the second parameter is false, there should be one fibre-sheet definition for each element; otherwise there should be one fibre-sheet definition for each *quadrature point* in the mesh. In the first case, the file should be a .ortho file (ie each line has the fibre dir, sheet dir, normal dir for that element), in the second it should have .orthoquad as the format.

Parameters:

	orthoFile	the file containing the fibre/sheet directions
	definedPerQuadraturePoint	whether the fibre-sheet definitions are for each quadrature point in the mesh (if not, one for each element is assumed).

void AbstractCardiacMechanicsSolver< DIM >::SetCalciumAndVoltage	(	std::vector< double > &	rCalciumConcentrations,
		std::vector< double > &	rVoltages
	)			`[inline]`

Set the intracellular Calcium concentrations and voltages at each quad point. Pure.

Implicit solvers (for contraction models which are functions of stretch (and maybe stretch rate) would integrate the contraction model with this Ca/V/t using the current stretch (ie inside AssembleOnElement, ie inside GetActiveTensionAndTensionDerivs). Explicit solvers (for contraction models which are NOT functions of stretch can immediately integrate the contraction models to get the active tension.

Parameters:

	rCalciumConcentrations	Reference to a vector of intracellular calcium concentrations at each quadrature point
	rVoltages	Reference to a vector of voltages at each quadrature point

virtual void AbstractCardiacMechanicsSolver< DIM >::Solve	(	double	time,

void AbstractCardiacMechanicsSolver< DIM >::ComputeDeformationGradientAndStretchInEachElement	(	std::vector< c_matrix< double, DIM, DIM > > &	rDeformationGradients,
		std::vector< double > &	rStretches
	)			`[inline]`

Compute the deformation gradient, and stretch in the fibre direction, for each element in the mesh. Note: using quadratic interpolation for position, the deformation gradients and stretches actually vary linearly in each element. However, for computational efficiency reasons, when computing deformation gradients and stretches to pass back to the electrophysiology solver, we just assume they are constant in each element (ie ignoring the quadratic correction to the displacement). This means that the (const) deformation gradient and stretch for each element can be computed in advance and stored, and we don't have to worry about interpolation onto the precise location of the cell-model (electrics-mesh) node, just which element it is in, and ditto the electric mesh element centroid.

To compute this (elementwise-)constant F (and from it the constant stretch), we just have to compute F using the deformed positions at the vertices only, with linear bases, rather than all the nodes and quadratic bases.

Parameters:

	rDeformationGradients	A reference of a std::vector in which the deformation gradient in each element will be returned. Must be allocated prior to being passed in.
	rStretches	A reference of a std::vector in which the stretch in each element will be returned. Must be allocated prior to being passed in.
