Detailed Description
template<class ELASTICITY_SOLVER, unsigned DIM>
class ImplicitCardiacMechanicsSolver< ELASTICITY_SOLVER, DIM >
Implicit Cardiac Mechanics Solver
The first template parameter should be either IncompressibleNonlinearElasticitySolver or CompressibleNonlinearElasticityAssembler; this will be the class that this class ultimately inherits from.
Solves cardiac mechanics implicitly (together with the contraction models for determining the active tension), taking in the intracellular calcium concentration. See CardiacElectroMechanicsProblem documentation for more detail.

A method called by AbstractCardiacMechanicsSolver::AssembleOnElement(), providing the active tension (and other info) at a particular quadrature point. This version uses C to determine the current stretch and stretch rate, and integrates the contraction model ODEs to determine the active tension, and derivatives of the active tension with respect to stretch and stretch rate.
- Parameters:
-
currentFibreStretch The stretch in the fibre direction currentQuadPointGlobalIndex Quadrature point integrand currently being evaluated at in AssembleOnElement. assembleJacobian A bool stating whether to assemble the Jacobian matrix. rActiveTension The returned active tension rDerivActiveTensionWrtLambda The returned dT_dLam, derivative of active tension wrt stretch rDerivActiveTensionWrtDLambdaDt The returned dT_dLamDot, derivative of active tension wrt stretch rate

Solve for the deformation using quasi-static nonlinear elasticity. (not dynamic nonlinear elasticity, despite the times taken in - just ONE deformation is solved for. The cell models are integrated implicitly over the time range using the ODE timestep provided, as part of the solve, and updated at the end once the solution has been found, as is lambda.
- Parameters:
-
time the current time nextTime the next time odeTimestep the ODE timestep
