solving a parabolic partial differential equation.
which is worse: having too fine timestep or too fine grnd?

By CFL condition, too fine grids must mean that you have to use
very fine time step.

i knew this. but i don't know too much about finite difference. so pardon
my ignorance. this is kind of an interview question.
then what's special about "parabolic" and "explicit"?
