Results Expressions and Probes New Features NX 10.0 CAE Results Expressions and Probes

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: 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 Example: Results probes contour plot of stress +/- stress error

Results Expressions and Probes Example: Stress margin calculation based upon temperature dependent yield stress Stress Margin = 1 – (Stress(x,y,z)/YieldStress(temperature))

Expressions CAE Plugin Functions 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

Expressions CAE Plugin Functions Example: Mass flow of a stream defined as a mixture of mass flows from 2 or more streams MMIX(8,11) : mixture of ST76 and ST36 to produce ST4 mass flow

Expressions CAE Plugin Functions Example: Compute clearance between two points in a model y(“pt1”) + dy(“pt1”) – y(“pt2”) – dy(“pt2”) :named references
