1、.数据准备(1)启动ABAQUS COMMAND(2)在COMMAND中输入abaqus fetch job=viewer_tutorial(3)在COMMAND中输入abaqus viewer(4)根据提示打开数据库viewer_tutorial.odbD.10Displaying and customizing an XY plotYou can display XY plots of data written to the output database. For the tutorial you will display the vertical displacement of the
2、 rigid body reference node versus time. The Visualization module also allows you to display XY plots of the following: Data read from an ASCII file. Data entered at the keyboard. Existing data, either combined with other data or arithmetically manipulated.以上内容讲的主要是根据数据库文件绘制所需变量与时间的曲线图D.10.1Displayin
3、g an XY plotYou will now display an XY plot of displacement versus time.To display an XY plot:1. In the Results Tree, click mouse button 3 on History Output for the output database named viewer_tutorial.odb. From the menu that appears, select Filter.2. In the filter field, enter *U2* to restrict the
4、 history output to just the displacement components in the 2-direction. 3. Double-click the data object containing the history of the vertical motion of the rigid body reference node: Spatial displacement: U2 at Node 1000 in NSET PUNCH.Abaqus displays an XY plot of displacement versus time, as shown
5、 in Figure D11. Figure D11 XY plot of displacement versus time.Default options selected by Abaqus include default ranges for the X- and Y-axes, axis titles, major and minor tick marks, the color of the line, and a legend. 4. The legend labels the XY plot U2 N: 1000 NSET PUNCH. This is a default name
6、 provided by Abaqus.以上操作如下图所示,如果输出变量列表中含有太多变量时,要找出我们想要的变量并不容易,这时就可以用输入”*U2*”表示2方向上的位移值,以去除列表中其余不必要的变量,便于选择,之后要把鼠标放在输出变量列表框里双击一下.接下来点击下面的”Plot”按钮就可以显示曲线了. 不过由以上操作过程可以看出,要显示这样的数据曲线,首先是需要我们在建模时就要要根据需要设置相应的节点集合和单元集合.比如这个数据库文件中就有下图所示的节点集和单元集.要不然就没法画这样的曲线图了.D.10.2Customizing an XY plotBy default, Abaqus c
7、omputes the range of the X- and Y-axes from the minimum and maximum values found in the data read from the output database. Abaqus divides each axis into intervals and displays the appropriate major and minor tick marks. The Axis Options allow you to set the range of each axis and to customize the a
8、ppearance of the axes; the Curve Options allow you to customize the appearance of the individual curves; the Chart Options and Chart Legend Options allow you to position the grid and legend, respectively. XY plot customization options apply only to the current viewport and are not saved between sess
9、ions.(这部分讲的主要是对曲线图进行相关的操作,这些操作主要包括:设置坐标轴的名称,单位;调整图域的大小;设置刻度线的长度,数量;是否显示栅格,是否有标题栏.自已摸索一下就OK了,也可以跳过不看)To customize an XY plot:1. From the main menu bar, select OptionsXY OptionsAxis (or click in the prompt area to cancel the current procedure, if necessary, and double-click either axis in the viewport
10、).Abaqus displays the Axis Options dialog box.2. Switch to the Scale tabbed page, if it is not already selected.3. Specify that the X-axis should extend from 0 (the X-axis minimum) to 20 (the X-axis maximum) and that the Y-axis should extend from 200 (the Y-axis minimum) to 0 (the Y-axis maximum).Ti
11、p: Select each axis in turn in the Axis Options dialog box, and then edit the scale as noted above.4. From the options in the Axis Options dialog box, do the following. In the Scale tabbed page, request that major tick marks appear on the X-axis at four-second increments (select By increment in the
12、Tick Mode region of the page). Request 3 minor tick marks per increment along the X-axis (this corresponds to a minor tick mark every second) and 4 minor tick marks per increment along the Y-axis (this corresponds to a minor tick mark every 10 mm). In the Title tabbed page, type a Y-axis title of Di
13、splacement U2 (mm). In the Axes tabbed page, request a Decimal format with zero decimal places for the Y-axis labels.5. Click Dismiss to close the Axis Options dialog box.前面几步主要是设置坐标轴,可按下图操作,主要就是弄明白四个属性页的意思就可以了,SCALE是调整坐标和显示比例的,Trik Marks是用来调整刻度线的长度,线型,数量的. Title是用来设置坐档轴的名称,单位的.Axis是用来设置曲线的线型颜色的.6.
14、From the main menu bar, select OptionsXY OptionsChart (or double-click any empty spot in the plot) to modify the grid lines and position the grid.a. In the Chart Options dialog box that appears, switch to the Grid Display tabbed page.b. Toggle on Major in both the X Grid Lines and Y Grid Lines field
15、s. Change the color of the major grid lines to blue; the line style should be solid.c. Switch to the Grid Area tabbed page.d. In the Size region of this page, select the Square option.e. Use the slider to set the size to 75.f. In the Position region of this page, select the Auto-align option.g. From
16、 the available alignment options, select the fourth to last one (position the grid in the bottom-center of the viewport).h. Click Dismiss.以上说了这么多也同什么,就是用来调整图弄的显示区域的大小了,总共就二个属性页,很了看的)1. From the main menu bar, select OptionsXY OptionsChart Legend (or double-click the legend) to position the legend.a. In the Chart Legend Options dialog box, switch to t
