WHAT IS RECENT IN STUDY SETUP
June 13, 2019 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.©
NEW MODEL TYPES
• Lookup – to import and explore any tabular data (*.csv)
Use case: Build a fit on a measurements dataset
• HyperStudy Fit – to import a Fit (*.pyfit report file)
Use case: Share fit models between different studies and users
ex. Perform multi domain exploration
• FluxMotor – to connect to FluxMotor motor design tool
Use case: Optimize a motor at the predesign stage
(ex. optimize the motor efficiency over WLTP driving cycle)

• B PreProcessor – to connect to ANSA pre-processor

MODEL IMPROVEMENTS
• SimLab model has been improved in 2017.2.2
• To parametrically drive SimLab macros (.js), which can be used to automatically mesh
and solve FEA problems (ex. OptiStruct)
• To automatically detect and import parameters and responses
• FEKO, Flux and Spreadsheet
• Multi-execution support

MODEL RESOURCES
• Add File input resource
• Add Folder resource
• Add linked output resources
• Model dependencies visualization

VARIABLE CONSTRAINTS
• Expressions in function of variables
• Avoid failed solvers calls by
truncation sampling (DOE,
optimization)
• Can be used with D-Optimal, MELS,
ARSM, GRSM, GA, MOGA
• If constraints defined, sweep and
system bounds check are not
available

FILE ASSISTANT
• Guided Responses and Data Sources creation
• String filtering, Slice and dice✓ Extract min, max of a curve or a set of curves
✓ Get individual or combined data sources and responses

MODES TRACKING AND MATCHING
• Modal Assurance Criteria (MAC) calculation✓ Maximize MAC to match simulation to test
✓ Constrain modes as they switch (similar to OptiStruct MODETRAK)

WHAT IS RECENT IN APPROACHES
June 13, 2019 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.©
NEW FIT METHOD
• Fit Automatically Selected by Training (FAST)
• selects the best available Fit from a list of available methods
• In Settings tab you can review or modify the available methods
(by default all of the methods are selected)
• automatically adjusts the individual settings to find the
optimizing, predictive performance while avoiding overfitting
• uses the cross-validation R2 for Fit quality comparison
between methods

NEW RBDO METHOD
• System Reliability Optimization (SRO) method
• Considering system reliability requirements rather
than individual constraints
• True multi-objective trade-off for robust design
• High Efficiency

positive effects for
dvs interactions
June 13, 2019 Altair Engineering, Inc. Proprietary and Confidential. All rights reserved.©
NEW ORDINATION PLOT
• Analyze a biplot from a Principle Component Analysis (PCA) • Visualize dimension reduction
• Investigate on positive and negative correlations• Lines that point in the same direction have strong correlations (positive or negative depending on
whether the lines point in the same or opposite directions)
• The relative length of the lines also indicates a strong correlation

BUBBLES
• New Bubbles tab in Scatter and Optima tabs
• Visualization of 3rd and 4th dimension on scatter
• Very important in Multi-objective optimization with more than 2 objectives

MORE INTUITIVE FIT DIAGNOSTICS
• Summary table with the main information
• Fit type and settings
• R-Square
• Spark lines and color coding to read R-Square values:
• Red (R2 < 0.65) - indicates the value is not good
• Green (0.8 < R2 < 0.995) - indicates the value is good
• Black - indicates that you should apply judgment
to determine whether the value is good or not
• Detailed diagnostics still available for each
response

SIMPLER OPTIMIZATION DEFINITION
• New Responses table
• Summary view of all responses
• Define, modify and review Objectives and Constraints for all responses
• Disable Active check boxes for responses, which are not used in the optimization
• Change the evaluation source (solver or fit) for responses individually or for all
responses together using the Evaluate from Fit Model feature
