Sources and Sinks
Sources and sinks are used to generate contaminants within and remove contaminants from zones. Sources can be used to simulate building materials such as carpet, pieces of furniture, and episodic events such as the use of cleaning products. You can define an almost unlimited number of sources within a project.
To implement a source/sink, you must first define the species with which you want the source/sink to be associated. You then place a source/sink icon within a zone on the SketchPad. Once you place source/sinks on the SketchPad, you can define their characteristics, move, copy, and delete them.
Much of the information that describes the characteristics of a source/sink is contained in source/sink elements that you must create when defining source/sinks.
Source/Sink Elements
CONTAM uses mathematical relationships referred to as source/sink elements or models to implement sources and sinks when performing contaminant simulations. CONTAM provides you with several source/sink models to choose from. Every source/sink must refer to a single source/sink element; however, multiple source/sinks can refer to the same source/sink element which can also be stored within a CONTAM library file and shared between different CONTAM project files.
