- romAI
  - Introduction
    romAI is an application that is comprised of libraries from the Altair Composeand Altair Twin Activate software products.
  - Design Fundamentals
    romAI serves two purposes.
  - Theoretical Framework
    Some system theory terminology must be understood.
  - ROM Framework
  - Workflow
    The typical workflow has four steps.
  - Installation
    The romAI tool is enabled through Extension Manager.
  - GUI
    The first steps of the workflow are accomplished through the GUI.
  - Pre-Processor Tab
    The Pre-Processor tab contains the optional pre-processing step.
  - Builder Tab
    The Builder tab facilitates the training step.
  - Post-Processor Tab
    The Post-Processor tab lets you visualize and evaluate the trained ROM.
  - ROM Generation Tips
  - Batch Training
    The training procedure can be carried over without using the GUI.
  - Batch Execution
    The simulation and evaluation of a romAI model can be also done via batch in the Compose OML editor without the need to deploy the trained romAI model into a Twin Activate block, using the romAI_execute function.
  - romAI Block
    After you install the romAI library in Twin Activate, a new palette appears in the Palette Browser.
  - Examples
    - Battery Cell Thermal Behavior
    - Nonlinear Spring Mass Damper System
    - Bucket into Pile of Bulk Material
    - Auto Exploration
    - Repeat Training
      During the training of a model in romAI, the Neurons are initialized randomly therefore two models can predict different values even though they have been trained with same Hyper Parameters.
    - Finite-State Machine Mass Spring Damper System
    - 2DoF Pendulum
      An example of a mechanical system of a pendulum in a cart.
