Detailed Description

Function Documentation

gridWalkTest() [1/2]

template<class DiscreteFunction , class Indicator >

void gridWalkTest

(

const BoundarySupportedFunction< DiscreteFunction, Indicator > &

f

)

Test routine which is called with the GridFunctionExpression from the main-program.

We simply walk over the grid and evaluate the local function and its jacobian on each boundary intersection.

References Dune::ACFem::BoundarySupportedFunction< GridFunction, Indicator >::localFunction().

gridWalkTest() [2/2]

template<class DiscreteFunction >

void gridWalkTest

(

const DiscreteFunction &

f

)

Test routine which is called with the GridFunctionExpression from the main-program.

We simply walk over the grid and evaluate the local function and its jacobian on each element.

main()

int main	(	int	argc,
		char *	argv[]
	)

Test-template main program.

Instantiate a single expression template and evaluate it on a simple grid.
