New Features NX 10.0 CAE
Results Expressions and Probes

2. 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

3. Results Expressions and Probes
Example: Results probes contour plot of stress +/- stress error

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

5. 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

6. 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

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