Variables at grid points

A variable corresponding to trilinear finite element functions can be defined as follows:

   Cylinder cylinder(R,r,l);
   Blockgrid grid(&cylinder,m);    // Construction of grid
    ...

  Variable<double> f(grid);

    ...

Now, u represents a piecewise trilinear continuous function on the grid grid .
