Use an Annotation plot (
) to add an annotation anywhere in a plot. You can add
Annotation subnodes to any plot group by right-clicking the plot group node and selecting
Annotation. Add
Deformation,
Transformation,
Transformation (3D only), or
Visual Effects (3D only) subnodes as desired. If you want to use a Deformation subnode to move the annotation in accordance with some other deformed plot, typically, use expressions to define the deformation vector and select the other plot in the
Inherit Style section to inherit the plot style from the plot that you want the annotation to move in accordance with.
This section is only available for an Annotation node under a
1D Plot Group that use two
y-axes. In that case, select the
Plot on secondary y-axis checkbox to plot the annotation using the coordinates for the secondary
y-axis. You can also specify the axis to use in the
Plot Settings section in the settings for the
1D Plot Group node.
In the Text field, type the text that you want to display as an annotation. If you want the annotation to also contain the position (displayed before the annotation text), select the
Prepend the position checkbox.
Select the LaTeX markup checkbox if you want to include mathematical symbols and Greek letters, for example, in the annotation. To include such symbols, surround the LaTeX syntax with
$ (so-called math mode) to indicate that the text inside of the
$ signs is LaTeX. For example,
$\alpha = \beta/\pi$ appears as
α = β/π. If the
LaTeX markup checkbox is selected, you can also add line breaks as
\\. See
Mathematical Symbols and Special Characters for more information about available LaTeX symbols and characters (of which most but not all are applicable in this context).
You can include the value of some variable in the annotation. For example, type eval(T) to evaluate the temperature
T in the annotation position, or
eval(t,min) to evaluate the time
t (in minutes). Use an optional third argument to eval to control the precision as an integer. For example,
eval(t,min,3). If there is no unit, you can leave the second argument empty.
You can also use printf-style number format specifiers of the form
%[flags][width][.precision]type as the last argument using the syntax
eval(expr,unit,precision), where the unit is optional. Allowed types are {
d,
f,
e,
E,
g,
G}. Two examples are
eval(pi,,%05d), which appears as
00003, showing the number as a rounded integer with the width of 5 and zero padding, and
eval(pi*1e10,,%+.3e), which appears as
+3.142e+10, a number with scientific format with 3 decimal values and with the sign of the number shown.
From the Geometry level list, you can select the geometry level for the evaluation:
From dataset (the default),
Volume (3D only),
Surface,
Line,
Point, or
Global. Click the
Replace Expression (
) or
Insert Expression (
) button to select predefined expressions to use inside of the
eval statement.
In the x,
y, and
z fields (for a 3D model with Cartesian coordinates; coordinate names can vary), enter the positions of the annotation as space-separated coordinate values. If you want to evaluate an expression that is defined in the geometry, the positions must be within the geometry. Click the
Range (
) button to define a range of values for a coordinate. Click the
Replace Expression (
) button to select predefined expressions to use as positions of the annotation. For example, if you have added a
Mass Properties node and created variables for the center of mass, you can choose them to place the annotation at the center of mass.
From the Expression number format list, choose one of the following formats:
|
•
|
Default: Numerical values that come from the solvers are presented as-is. Numbers formatted during postprocessing use the Output display precision preference setting.
|
|
•
|
Automatic: All numbers are formatted using the specified precision that you enter in the Precision field (default: 6). Select the Show trailing zeros checkbox if you what to display trailing zeros.
|
|
•
|
Engineering: All numbers are formatted using engineering notation (such as 31.416E-6; it is similar to scientific notation but with the powers of ten as multiples of three) using the specified precision that you enter in the Precision field (default: 6). Select the Show trailing zeros checkbox if you what to display trailing zeros.
|
|
•
|
Scientific: All numbers are formatted using scientific notation (such as 3.1416E-5) using the specified precision that you enter in the Precision field (default: 6). Select the Show trailing zeros checkbox if you what to display trailing zeros.
|
|
•
|
Stopwatch: All numbers are formatted in decimal notation with a specified number of integer digits and decimals, which you enter in the Number of integer digits field (default: 3) and Number of decimals field (default: 2), respectively. Unnecessary zeros are always shown. For example, with the default settings, 17.1 would be formatted as 017.10. The specified number of integer digits is not respected if the number is too large or if it is NaN or Inf. Select the Always show the sign checkbox to keep the width from changing for a sequence that includes both positive and negative values. Select the Always show the imaginary part checkbox to keep the width from changing for a sequence that includes both real numbers and numbers with a nonzero imaginary part.
|
|
•
|
Scientific stopwatch: All numbers are formatted in scientific notation with one integer digit and a specified number of decimals and exponent digits. For example, with the default settings, 17.1 would be formatted as 1.71E1. The settings are the same as for the Stopwatch format, with the addition of an Always show the sign of the exponent checkbox. Select it to keep the width from changing for a sequence that includes both positive and negative exponents.

The Recover default is
Off because recovery takes processing time. To use polynomial-preserving recovery and recover fields with derivatives such as stresses or fluxes with a higher theoretical convergence than smoothing, from the
Recover list, select
Within domains to perform recovery inside domains or
Everywhere to apply recovery to all domain boundaries.
Clear the Show point checkbox if you do not want to include a point in the plot at the location of the annotation. If desired, and if the
Show point checkbox is selected, change the value in the
Point radius field (default: 2) to a value between 0 and 1 to adjust the point size.
From the Color list, choose the color to use for the annotation text. Choose
From theme (the default) to use the color from the current color theme, or choose
Custom to choose a custom color from a color palette. Select the frame background color from the
Background color list. Choose
From theme to use a background color that changes with the selected color theme.
From the Anchor point list, choose the position of the anchor point relative to the annotation text:
Upper right,
Upper middle,
Upper left (the default),
Middle right,
Center,
Middle left,
Lower right,
Lower middle, or
Lower left.
From the Orientation list, choose
Horizontal (the default) or
Vertical, if you want the annotation text to be displayed vertically instead of horizontally.
Select the Show frame checkbox to display the annotation in a rectangular frame.
