A parallel solver for anisotropic cardiac models

A parallel solver for numerical simulations of a full cardiac cycle in three dimensional domains, based on the anisotropic monodomain and bidomain models, is presented. The solver employs structured isoparametric trilinear finite elements in space and a semi-implicit adaptive method in time. Parallelization and portability are based on the PETSc parallel library. Large-scale parallel computations have been run, simulating anisotropic dispersion of the action potential duration.
