I added
grid->SetNumberOfScalarComponents(1);

before the triple loop setting the components
grid->SetScalarComponentFromDouble(x,y,z,0,d);

and there was no change. The resulting polydata still has 0 points and
cells, and Increments is still (0,0,0).

As I typically request of other users, here is a compilable example
that produces the problem:
