Objective: Define scalar expressions that generate new results from solution results in a more managed and repeatable way

Implementation:

Results expressions to define variables input to probes

Results probes to define expressions and be evaluated to generate output

• Contour plot of entire model

• XY graphs

• Fields

• Information

Results expressions defined in Menu Insert, Result Expressions

Probes defined and managed from solutions

Results Expressions and Probes

Applications:• Results combination

• Stress +/- stress error

• Clearance between 2 points • Initial position and displacement

dependent

• Histories at discrete locations• Points, edges, faces

• Lookups to results dependent properties such as temperature dependent material• Safety margin using a temperature

dependent yield stress

Objective: Provide functions that represent commonly used variables in expressions

Implementation:

CAE plugin functions

• Used by expressions defining LBCs and results probes

• Solver specific functions evaluated during the solve (Thermal)

• General and solution dependent functions

• Evaluated based upon entity name or ID
