Model Reference Guide

Parameters

This page defines the configurable parameters available in FastEddy®. Parameters are organized into logical sets by model feature or model configuration component.

Each table provides the:

  • Parameter name: Description

  • Minimum value (if applicable)

  • Maximum value (if applicable)

  • Default value (if applicable)

  • Req. (Requirement)

    • M (Mandatory)

    • O (Optional)

    • C-M (Conditionally Mandatory, with the condition listed in the description)

    • C-O (Conditionally Optional, with the condition listed in the description)

These definitions serve as a reference to ensure correct configuration and valid inputs for FastEddy simulations.
