For static studies, you can create result plots that are defined with equation expressions from existing result variables.
To open the
Results Equation Plot PropertyManager:
 Run a static study.
 Rightclick Results and click Results Equations.
The Results Equation Plot is available for static, nonlinear static, nonlinear dynamic, linear dynamic, thermal, drop test, submodeling, and pressure vessel studies. You can only combine result parameters from the active study.
Equation Plot Options

Legend title text

Type the legend title of the results equation plot. You can type custom units in the legend title text.


Results Equation

Displays the equation that drives the result plot. 

Units

Sets the unit system. 

Edit Equation

Opens the equation editor. Select Node Values or Element Values to filter the result parameters.
Click the edit equation box to activate admissible functions, stress, strain, displacement, or thermal variables.
Functions

Lists the permissible mathematical functions to use in the equation.

Stresses

Lists allowable stress parameters.

Strains

Lists allowable strain parameters.

Displacements

Available for node values. Lists allowable displacement parameters.

Thermal

Available for thermal studies. Lists allowable thermal parameters.


Advanced Options

Shell face

Available for shells only. Select one the following:
Top

Total stress values (bending + membrane) at the top face. For composite shell, Top refers to top face of selected ply in Ply number under Composite Options.

Bottom

Total stress values (bending + membrane) at the bottom face. For composite shell, Bottom refers to bottom face of selected ply in Ply number under Composite Options.

Membrane

Membrane stress component

Bending

Bending stress component



Show plot only on selected entities

Generates plots only for the selected entities. 
Composite Options
Available only for composite shells.

Maximum across all plies 
Considers the maximum stress values of the specified component (envelope plot) across all plies. The program includes the Top and Bottom faces while searching for the extreme value across all plies. 

Ply number 
Selects the ply number to calculate the stress. This option is not available when you select Maximum across all plies.
