Multigrid

Hello all,

I'm still trying to wrap my head around the use of the multigrids
CP2K.   From my understanding if I were to go from using 4 grids to 2,
it would affect the efficiency of the calculation.  However, I don't
know if that would affect the accuracy of the results (given the fact
that the finest grid remains the same between the two calculations).
Can someone tell me if changing the number of multigrids affects the
accuracy of a calculation?

Thanks,
Corey
