Abstract
The fractal structure of directed percolation clusters, grown at the p ercolation threshold inside parabolic-like systems, is studied in two dimensions via Monte Carlo simulations. With a free surface at y = +/- Cx(k) and a dynamical exponent z, the surface shape is a relevant pert urbation when k < 1/z and the fractal dimensions of the anisotropic cl usters vary continuously with k. Analytic expressions for these variat ions are obtained using a blob picture approach.
