Example b211x: Simple 2d simulation using Grid based FEM and AMG solver

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 used for this example is the serial version of Algebraic Multigrid with some OpenMP directives.

The comfile run by this example is as follows:

#Example b211t
# ------------
fem define para;r;box;example
fem define coor;r;box;example

fem define node;r;box;example
fem define base;r;box;example
fem define elem;r;box;example

fem define fibr;d
fem define elem;r;box;example fibre

fem define grid;r;box;example
fem update grid geometry
fem group grid external as boundary
fem define equa;r;box;example
fem group grid xi1=low as stimulus

fem define mate;r;box;example
fem define cell;r;box;example
fem define init;r;box;example
fem define solv;r;boxamg;example
fem solve to 0

fem def win

for $M ( 0..9 ) 
{
fem solve restart to $M
fem draw field grid 1 zmin=-85 zmax=40
fem dr grid 
refresh graphics
}
