CardiacElectroMechanicsProblem
For solving full electro-mechanical problems.
Solves a monodomain problem (diffusion plus cell models) on a (fine) electrics mesh, and a mechanics problem (finite elasticity plus contraction model) on a coarse mesh. An implicit scheme (Jon Whiteley's algorithm) be be used.
For solving problems on regular grids use CardiacElectroMechProbRegularGeom
The implicit algorithm:
Store the position in the electrics mesh of each quad point in the mechanics mesh For every time: Solve the monodomain problem (ie integrate ODEs, solve PDE) Get intracellular [Ca] at each electrics node and interpolate on each mechanics quad point Set [Ca] on each contraction model (one for each point) Solve static finite elasticity problem implicity
