Max/Min Volume, Max/Min Surface, and Max/Min Line
Use the Max/Min Volume (), Max/Min Surface 2D (), Max/Min Surface 3D (), Max/Min Line 2D (), and Max/Min Line 3D () plots to plot the maximum and minimum values of an expression and the points there they are attained within the geometry.
When plotting the maximum and minimum value, an associated table appears in the Table window (underneath the Graphics window if using the default COMSOL Desktop layout). The table contains the maximum and minimum values along with the coordinates for the corresponding locations. The coordinate columns’ titles contain the space variable names from the data set, if you use a Cut Plane data set, for example. Add a Deformation subnode as needed. Right-click a 2D Plot Group or 3D Plot Group to add these plots from the More Plots submenu.
Go to Common Results Node Settings for links to information about these sections: Data, Expression, Title, Coloring and Style, and Inherit Style.
Advanced
Under Advanced, define the number of refinements of each mesh element when computing the maximum and minimum by entering a value in the Element refinement field (the default is 2). Edit these other settings if required:
•
Enter a Display Precision for the number of decimals displayed in the labels. The default is 6.
•
If you want to add a prefix or a suffix to the labels for the maximum and minimum values, add them in the Prefix and Suffix fields. The same prefix and suffix are used for the maximum and minimum labels.
•
The Recover default is Off because recovery takes processing time. To edit the default and 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.
•
Select an option from the Display list: Min and max (the default), Min, or Max.
