We investigate the behavior of counterpropagating self-trapped optical beam structures in nematic liquid crystals. We treat numerically a time-dependent model for the beam propagation and the director reorientation in a nematic liquid crystal, in (2 + 1) spatial dimensions. The formation of stable s
