Abstract
Classical approximations for critical dynamics are taken as the basis of a new dynamical renormalisation group strategy in real space. The approach is phenomenological and avoids proliferation of interactions, as well as memory effects. For the square and cubic Glauber model, the best determinations of static critical properties come up with values for the dynamic exponent which appear compatible with the most recent estimates by Monte Carlo or series expansion methods.
