In this tutorial, you will learn how to:

•Create line plots from a file
•Create line plots using a math expression

Tools

The Define Curves panel can be accessed one of the following ways:

•From the toolbar, click the Define Curves icon, curvesCreate3D-24.

Or

•From the menu bar, select Curves > Define Curves

define_curves_panel_3d

The Define Curves panel enables you to edit existing curves and create new ones. New data can be selected from a source file, mathematically defined using the program's curve calculator, or entered as values.  The options in the panel change depending on which source is selected. If the source chosen is Math, the panel looks as shown below:

define_curves_panel_3d_math

The Curve list displays the names of all curves in the active window.  Curves can be renamed, added, cut, copied, and pasted using the curve list controls.

Exercise: Defining Line Plots.

Step 1: Creating a line plot from a file

1.Go to the Define Curves panel curvesCreate3D-24.
2.Click Add under the Curve list.

A curve labeled Curve 1 is added to the list.

3.Rename Curve 1 to Line Curve 1 and press ENTER.

The new name is now displayed in the list and in the legend.

4.Under Vector, select X.
5.Set the Source type as File.
6.From the dyna folder, select the file nodout.
7.Ensure X is selected for the vector.
-For Type, select Time.
-For Request, select Time.
-For Component, select Time.
8.Under Vector, select Y.
-For Type, select Node Data.
-For Request, select Nodal Point 26742.
-For Component, select Resultant Displacement.
9.Under Vector, select Z.
-For Type, select Node Data.
-For Request, select Nodal Point 26742.
-For Component, Resultant Displacement.
10.Click Apply.
11.Click Add under the curve list to add another curve.
12.Repeat steps 4 to 10 choosing Nodal Point 26766 as the Y and Z Request and Resultant Displacement as the Component.
13.(Optional) Plot for other Requests and Components.

Step 2: Create a line plot from a math expression.

1.Click the Add Page icon pageNew-24 to add a page or press the SHIFT and F3 keys.
2.Click Add under the curve list. A curve labeled Curve1 is added to the list.
3.Rename the curve to Math_curve.
4.The new name is now displayed in the list and in the legend.
5.For Source, select Math.
6.Under Vector, click All.
7.Set X to sin(2*u)*(10.0 + 6*cos(3*u)).
8.Set Y to cos(2*u)*(10.0 + 6*cos(3*u)).
9.Set Z to 6*sin(3*u).
10.Set U to 0:(2*PI):(PI/50).

all

11.Click OK to close the dialog.
12.Click Apply to create the plot.
