ADINA中的坐标系及其用途用法（The frame and its use in ADINA） Coordinate system (axis) in ADINA and its use and usage -- ADINA guangzhou wang xuechao So this is the coordinate axis The most basic content of ADINA, in modeling, initial / boundary conditions apply and results are processed Both play an important role in learning and mastering The important aspects that ADINA must master. Due to the Scaled of adina.the sit The label (axis) involves a wide range of content, which is necessary ADINAs coordinate system (axis) is summarized. The coordinate system in ADINA is mainly below Nine: Global System Local Coordinate System (Local Coordinate System) Skew System Geometry Triads (geometric coordinates frame) Element Local Coordinate System (unit Coordinate System) An ortho-tropic Axes System (orthonormal shafts used to align the initial strain axis or material axis) Initial Strain Axes (Initial Strain axis) Material Axes Result Transformation System (Result Transformation frame) These are the following Nine coordinate systems are introduced in detail. 1. Global System (integral coordinate System) Description: the whole coordinate system is in There is already default in ADINA, as shown in figure 1.1 it does not require users to define themselves, It cant be changed. The name of the coordinate system is 0. Purpose: applicable to ADINA modeling, solving, and post-processing all processes, by default, Scaled all adina.the All the results of modeling, solving, and post-processing can be based on this coordinate system. In addition, ADINAs solution can only be found In the whole frame, all the boundary, load and other information based on other coordinate systems will be automatically converted to the whole sitting Coordinate system. figure 1.1 Note: in reprocessing, marked X, Y, Z or The results of XX, YY, ZZ, XY, XZ and YZ are generally base The result of the whole frame, but for 3 - D plane stress type unit The results of YY and ZZ are units The results of the coordinate system can
