Example b21521: Activation over simple 2d domain

This example solves the bidomain equations on a 2d domain. The equations are solved implicitly and the FHN ionic current model is used. The collocation grid used is generated using the lattice scheme. There are several similar examples using the old method, particularly example b2129.

The comfile run by this example is as follows:

fem define para;r;biline

fem define node;r;biline
fem define base;r;biline;example
fem define elem;r;biline
fem define grid;r;biline;example
fem update grid geometry
fem update grid metric
fem group grid xi1 low as stim_point oneoff  
fem group grid external as boundary
fem define equa;r;biline;example class 1,2
fem define mate;r;biline;example class 1,2
fem define cell;r;biline;example class 1,2
fem update grid material class 1,2
fem define init;r;biline;example class 1,2
fem define solv;r;biline;example class 1
fem define solv;r;biline2;example class 2
fem define window
fem solve to 0 class 1,2
