Curved cross-section laminate mesh ( i.e., using an AMESH command ). ESYS, KCN assigns a coordinate reference system to the element. The default state, ESYS, 0, assigns global Cartesian coordinates to the elements. The user may input ( KCN ) either 0 for global Cartesian or a local coordinate system ( 11-n ). The local coordinate system must have been previously defined using the LOCAL command. Neither 1,2, or 3 ( global cylindrical, spherical, or toroidal ) can be input to the ESYS command. Therefore, even for a model that can be built or described using the global cylindrical coordinate system, a local cylindrical coordinate system with its origin at 0, 0, 0 must be defined and referenced in the ESYS command to properly define the material properties at the element coordinate system level. Implementing this consistent direction reference will simplify the postprocessing of the results. The resultant stresses in ANSYS are provided by default and referenced to the global Cartesian reference system. The results can be presented relative to other coordinate's systems using the RSYS command. The format of the RSYS command is RSYS, KCN. KCN can be 0 for global Cartesian, 1 for global cylindrical, 2 for global spherical, 11-n for local coordinate systems, or SOLU ( in menu mode: AS CALCULATED ) for reference to the element coordinate systems defined by the ESYS command. The results for any ANSYS analysis can be viewed ( or printed ) using RSYS ( 1 or 2, or 3 or 11-n ). Only by using the ESYS command can the RSYS, SOLU command be used to get results at the same time relative to multiple coordinate systems. If the ESYS command is not implemented, the results relative to the single-selected coordinate system 5
