Detailed Description

template<class Function>
class Kaskade::UniformSampler< Function >

Class that can sample a Function(View) on a uniform rectangular grid.

This is useful, when using higher order FunctionSpaceElement s or highly nonlinear FunctionViews on a relatively coarse grid. The output to PARAVIEW can then be performed in high resolution. The use together with EdgeScanner yields a nice visualization of these functions.

Moreover, it is possible to zoom into interesting regions by defining the area of sampling appropriately.

Here a sample of how an output of UniformSampler and EdgeScanner may look like:

UniformSampler()

template<class Function >

Kaskade::UniformSampler< Function >::UniformSampler ( Dune::FieldVector< typename Grid::ctype, spaceDim > const &  lb, Dune::FieldVector< typename Grid::ctype, spaceDim > const &  ub, Dune::FieldVector< typename Grid::ctype, spaceDim > const &  st, Function const &  fu, bool  dataIsScalar = Function::components==1  )

inline

Performs a uniform sampling of fu on the cuboid marked by lb, ub with stepsize st.

Parameters

lb	defines the lower bounds of the cuboid
ub	defines the upper bounds of the cuboid
st	determines the stepsize that is taken for sampling in each direction
fu	is a FunctionSpaceElement or a FunctionViews object: the function to be scanned
dataIsScalar	determines whether a vectorial or a multicomponent scalar VTK file is written
