Moist Air libraries contain blocks for the moist air domain, organized into elements, sources, and sensors. Connect these blocks together just as you would assemble a physical system. Use these blocks, along with the blocks from other Foundation libraries and the add-on products, to model multidomain physical systems.
The Utilities library contains the Moist Air Properties (MA) block, which lets you specify the air mixture properties in the connected circuit. This block provides several options for modeling trace gas properties. For more information, see Modeling Moist Air Systems and Modeling Moisture and Trace Gas Levels.
