The different patterns observed at a twist-grain-boundary-- (TGBA--) smectic-A (A) interface moving in a temperature gradient are quantified by measuring interface arclength scaling between two lengths characterizing these patterns. The ragged melting TGB_A-A interface results from the growth of TGBA filaments into oriented A. We attribute the destruction of TGBA when A grows into TGBA to the second-order nature of the TGBA-cholesteric transition. These results are interpreted within a defect lattice model.
