Source Card (CO2E)

This card allows the user to control sources and/or sinks of mass and energy by defining time-varying sources.  By definition, sinks are negative sources, and sources refer to an influx of mass or energy into a node.  Sources can be specified for interior or boundary nodes and are functionally analogous to Neumann type boundary conditions.   Sources are time varying; however, unlike boundary conditions, multiple sources may be applied to a node during the same time period.  The simulator controls time steps to agree with time transitions in sources.

• Descriptions of the various source type options for STOMP-CO2e are provided on the Card Options page.

• Formatting instructions for specifying sources for STOMP-CO2e are provided on the Card Syntax page.

• Examples of Source Cards for STOMP-CO2e with and without solutes and geochemistry are provided on the Card Examples page.
