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.

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.

) | [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.
