A bidimensnal (2D) thermotropic liquid crystal (LC) is vtigated wh Molecular Dynamics (MD) simulatns. The Gay-Berne mogen wh parameterizatn GB(3, 5, 2, 1) is ed to mol a lamic system. Spatial orientatn of the LC sampl is probed wh the nematic orr parameter: a sharp isotropic-smectic (I-Sm) transn is observed at lower prsur. At higher prsur, the I-Sm transn volv an termediate nematic phase. Topology of the orthobaric phase diagram for the 2D se differs om the 3D se two important rpects: 1) the nematic regn appears at lower temperatur and slightly lower nsi, and 2) the cril pot occurs at lower temperature and slightly higher nsy. The 2D lamic mol is ed to probe the stctural behavr of LC sampl unr strong nfement when eher planar or homeotropic anchorg prevails. Sampl subjected to circular, square, and triangular boundari are gradually oled to study how orientatnal orr emerg. Dependg on anchorg mo and nfg geometry, characteristic topologil fects emerge. Textur the systems are siar to those observed experiments and simulatns of lyotropic LCs.
