Detailed Description
template<class ELASTICITY_SOLVER, unsigned DIM>
class ExplicitCardiacMechanicsSolver< ELASTICITY_SOLVER, DIM >
Explicit cardiac mechanics solver for solving electromechanic problems where the contraction model is not stretch-rate-dependent (for those the implicit solver is needed).The first template parameter should be either NonlinearElasticitySolver or CompressibleNonlinearElasticityAssembler; this will be the class that this class ultimately inherits from.
The general explicit solution procedure is to do, each timestep: (0) [solve the electrics and interpolate Ca and voltage onto quad points (i) pass Ca and voltage to the contraction models (ii) pass the fibre stretch to the contraction models in case this is needed. (iii) integrate the contraction models in order to get the active tension (iv) solve for the deformation using this active tension.

Constructor
- Parameters:
-
contractionModel The contraction model. pQuadMesh A pointer to the mesh. outputDirectory The output directory, relative to TEST_OUTPUT rFixedNodes The fixed nodes pMaterialLaw The material law for the tissue. Defaults to NULL, in which case a default material law is used.

Get the active tension and other info at the given quadrature point. This is an explicit solver so just sets the active tension, it doesn't set the derivatives. It stores the stretch for the next timestep.
- 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. Unset in this explicit solver. rDerivActiveTensionWrtDLambdaDt The returned dT_dLamDot, derivative of active tension wrt stretch rate. Unset in this explicit solver.

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 explicitly over the time range using the ODE timestep provided then the active tension used to solve for the deformation
- Parameters:
-
time the current time nextTime the next time odeTimestep the ODE timestep
