教你如何设定ANSYS路径.docVIP

. . 关于ANSYS路径 一、看一下GUI，有个感性认识 注意：下表给出的是路径的基本要素。路径是通过point来定义的，这些points可以通过拾取节点或pionts在工作面上的坐标或points在总体直角坐标系中的坐标来定义。在建立模型的时候，不同节点可能属于不同的坐标系。 通过pionts在工作面上的坐标来指定points（这些points可以不在模型上） 通过points在总体直角坐标系中的坐标来定义points 二、例子――使用路径 Path Name: Eight character (maximum) name assigned by the user. Defining Points: These are points in space or nodes. The path exists as line segments between these points. You can have up to 1000 of these. Interpolation Points: ANSYS creates internal points evenly spaced along each line segment in the path. It interpolates the data you ask for at these points. Path Items: These are the values interpolated from the model that are stored along the path. Each path comes with four default items: XG, YG, ZG, and S. The first three are the X, Y, Z position of each interpolation point and the distance of the point along the path, S. The user defines up to PATH, 路径的名字, 用于定义路径的point的个数（默认为2个）, 数据集数data set（默认为4个，x,y,z坐标，距离S）默认是30个, 相邻两个用于定义路径的point之间划分分段数，默认分为20份，没有上限。 path,exmp1,2,8,20 PPATH, P(鼠标拾取)/路径点号（point number）,节点号（如果节点号指定的话，后面的通过point坐标将被忽略,总体直角坐标系下point的x坐标, point的y坐标, point的z坐标,在前后points之间生成internal points时要用的坐标系（如果这个地方什么也不填，将会用当前活动坐标系；如果前后两点的坐标系不同，将会用后面一点的坐标系） ppath,1,,0,0,.25 1号point在总体直角坐标系下的坐标； ppath,2,,0,0,1.25 2号point在总体直角坐标系下的坐标；1、2point间的Interpolation Points生成用的是默认的当前活动坐标系 PDEF,最多8个字符的Path Items label , Items , Comp, 对单元结果是否进行单元间的平均处理（默认要作平均处理） pdef,ux,u,x pdef,uy,u,y pdef,uz,u,z pdef,usum,u,sum /yrange,-4,12 plpath,ux,uy,uz,usum 三、其他的一些常用的有关路径的命令 PATH This is the big command that sets up a path. Also use it as PATH, name to change the active path. PPATH Defines the points for the path. PMAP Used to define how the interpolation points are distributed. By default they are even, but with this command you can put refinement at the ends of each line segment or force a point at a discontinuity.(Accurate divisns) PDEF Does the interpolation from the model of solution values. PVECT Does the interpolation from the model of geometry va
