Altair Material Data Center
Altair Material Data Center (AMDC) provides accurate multi-domain material properties to enable the creation of sustainable, efficient, and lightweight designs.
View Material Details
Visualize advanced and accurate material properties and curves. Also, view material impact using Global Warming Potential (GWP) and set your data preferences.
Materials Intelligence
Materials sometimes have gaps in the data, making them difficult to use in simulations. Materials Intelligence is an powerful tool that fills these gaps in the data using various methods such as borrowing data from generic materials or predicting missing values using Artificial Intelligence (AI). This enables previously unusable materials for certain CAE applications and makes the same material suitable for different disciplines, supporting multiphysics simulations. Material Intelligence settings can be configured globally for all materials in the database or locally when viewing an individual material.

Altair Design AI
Altair DesignAI enables you to make real-time predictions.

Use Artificial Intelligence to Fill Gaps

For materials artificial intelligence can be used to predict missing material data.

Before you begin:

By default, the Artificial Intelligence option is enabled in the Preferences menu.
Ensure, Artificial Intelligence toggle is on to fill the missing data. You can enable this setting for a selected material individually.
If neither Generic Data nor Artificial Intelligence is available for a material, the toggle buttons will be grayed out.
Also, you can choose between Generic Data or Artificial Intelligence based on your need.

To fill gaps in material data, the advanced AI algorithm identifies similar materials with comparable properties and material types. It then predicts the missing data based on these similarities.

The AI algorithm selects materials for prediction based on material composition and key properties such as tensile modulus, yield stress, yield strain, and stress & strain at break.
The current AI implementation focuses on predicting stress-strain data for polymers.
The AI-prediction doesn't support when either yield stress & yield strain or stress at break & strain at break are unavailable.
The system cross-validates generated data with known material trends to improve reliability for CAE simulations.

To fill missing property values for stress-strain curves and related properties with AI predicted data for a material:

Select a material data set.
In the following example, ABS material data set from Polymer is selected.

The material database is filtered and displays the results.

Click Details of a required material.
A window opens to the right displaying the material information.
To select the AI gap filling tool for a material, on the top-right corner, select Materials Intelligence > Artificial Intelligence.

The AI tool predicts data and fills the missing curve data for the selected material. The stress-strain data for Plots is displayed.
Note: The AI-predicted curve data is labelled as AI.
