Volume Maximum, Volume Minimum, Surface Maximum, Surface Minimum, Line Maximum, and Line Minimum
The derived maximum and minimum values are useful for calculating maximum or minimum quantities for each solution in a dataset (a time-dependent solution, for example). Also apply an average, maximum (or minimum), or other operation to compute the maximum or minimum over the entire dataset for a quantity, for example.
Under Results, right-click Derived Values () or any Evaluation Group node (), and from the Maximum or Minimum submenus select:
•
Volume Maximum () or Volume Minimum () to evaluate a maximum or minimum value over a set of domains in 3D models. The result of the evaluation is stored in a Table and displayed in the Table window.
•
Surface Maximum () or Surface Minimum () to evaluate a maximum or minimum value over a set of domains in 2D, 2D axisymmetric, or boundaries in 3D.
•
Line Maximum () or Line Minimum () to evaluate a maximum or minimum value over a set of domains in 1D, boundaries in 2D, or edges in 3D.
Configuration
Choose to find the maximum or minimum of the real part or the absolute value, which are different for complex-valued data. Choose Real part (the default) or Absolute value from the Find maximum of or Find minimum of list.
Select the evaluation point type from the Point type list, if the maximum or minimum is taken for a geometry entity level that is lower than for the data in the dataset; otherwise, specify an Element refinement (default: 5):
•
 Lagrange points (the default) to evaluate the maximum or minimum value in the Lagrange points. Select a Lagrange order (default: 5; the Lagrange order is the number of partitions of an element edge) to adjust the accuracy of the minimum or maximum values.
•
 Node points to evaluate the maximum or minimum value in the node points of the extended mesh.
•
 Gauss points to evaluate the maximum or minimum value in the Gauss points (integration points). Select an Integration order (default: 4) to adjust the accuracy of the minimum or maximum values.
Select the Include position check box to also tabulate the position coordinates for the maximum or minimum.
