mkIC(ICeq, unknown_list, params_list, bsf_file);

Parameters:

ICeq - A list of equations specifying initial conditions. Each entry in the list is an equation of the form u(x,y)=expr, where u(x,y) is a variable in unknown_list. Those variables in unknown_list which do not appear on the left hand side of an equation in ICeq, are set to zero initially.

unknown_list - The list of unknowns as discussed above.

params_list - A list of scalar input parameters.

bsf_file - A file containing a Maple description of a particular finite element.

• Generates the code needed to set initial conditions. During execution the names of generated subroutines are echoed. The equations in ICeq are projected onto the test functions and the initial conditions are solved for using conjugate gradients.
• Those variables in unknown_list which do not appear on the left hand side of an equation in ICeq, are set to zero initially.

Examples:

> # make initial conditions. ic_eq is on the form 'unknown = expr':
> # variables that do not enter in lhs of an ic_eq are given the
# intial value 0:
> mkIC([ v(x,y)=x*x+y*y ], unknown_list, params_list ,
