Default sampling theorem and cfd

How does the sampling theorem commonly found in DSP texts fit in with CFD? Is it as simple as setting the timestep used in discretizing an equation (I'm thinking finite difference scheme in the meantime) to at least twice the reciprocal of the highest frequency present in the continuous equations/model? What about the spatial discretization? Thanks for shedding any light on this issue.. Luis
