Combination
Video: Combine results using a formula
The Combination command uses standard expression syntax to perform operations on one or more results of the same type. Selected result types are assigned an expression name automatically, which you can edit as needed. You can define a formula using any combination of named expressions (including user expressions), expression operators, and math functions.
The selected results may belong to different load cases, iterations, or solutions, but must be the same in terms of components (real or complex), output location, and solution type. If the selected result type consists of vector or tensor data, the specified formula is applied to each component individually. Derived results (for example, von Mises stress) are then calculated from the combined components.
When you use Combination to combine results, all vector and tensor component data is preserved. The following figure shows different component and derived contours for the sum of element-nodal stress results for three loadcases.
Clockwise from top left: YY stress, YZ shear stress, ZX shear stress, von Mises stress.
