Example b211t: Simple 2d box simulation using grid-based Finite Elements

This example is a simple 2d box which is solved with a time integration parameter of 0.5 using a cubic ionic current model. This example uses the Grid-based Finite Element method.

The solver options for this problem are the optimised options for the Grid-based FE method. (For large problems, a Conjugate gradient iterative solver with Symmetric succesive relaxation preconditioning is the most efficient).

The comfile run by this example is as follows:
