gridWalkTest()

template<class GridFunction >

void gridWalkTest

(

GridFunction &&

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.
