An Introduction to Material Definitions in CFD

Modeling AEC applications with Autodesk Simulation CFD relies on the proper assignment of fluid, solid, and device materials. Examine the effects of material characterization in AEC applications and gain practice using the simulation process.

Learning Objectives

  • Become familiar with material and device types.
  • Gain hands on familiarity by creating custom materials and devices.
  • Quantify the effects of material characterization on simulation results.

The use of Autodesk Simulation CFD to model AEC applications will require the proper assignment of materials.  Standard materials are comprised of fluids (e.g. air, water) and solids (e.g. wood, steel).  Devices are special types of materials that have been developed to represent complex AEC components such as filters, fans and air conditioning units

This module will discuss the effects of material characterization and give examples of material device definitions commonly used in AEC applications.


Typical AEC applications, such as this lab room, will require fluids, solids and devices to be assigned to the volumes and surfaces representing the simulation domain.
