  We study pattern formation in gels undergoing simultaneous phase separation
and orientational ordering. A 2D numerical simulation is performed using a
minimal model of nonlinear elasticity with density-anisotropy coupling. For
strong positive coupling, the collapsed phase elongates along the phase
boundary and buckles, creating a folded structure with paired topological
defects. For negative coupling, soft elasticity of the swollen phase causes a
droplet morphology as in liquid-liquid phase separation. Their possible
realizations in nematic liquid-crystalline gels are discussed.
