Additional Optional Sections

A. Sources

The Sources section begins with the keyword \SOURCES followed by the complete grid matrix like in the \PLANTS section.
This section defines the position of different sources in the model domain. As the concept is the same as for plants, this section is not displayed here.
Any source will be referenced using the two-char ID as defined in SOURCES.DAT or a Local Database. The two-char ID is non-case sensitive, “XX” is the same as “xx”!
Sources that are inserted in the Area Input File but cannot be found in a database when starting the model will be ignored.

B. Receptors

Receptors inside the model area are defined using the \RECEPTOR section. The concept is the same as for the plants explained in the section before. Each receptor is defined by a unique two-char ID. If duplicate receptors are found, the first defined receptor is used, the others are ignored. For more information about receptors click here.

The database section has no function in ENVI-met. It is used for other programs such as BOTworld (see UNCONVERTED WINHELP MACRO:! ExecFile www.botworld.info) to link certain grid points with database entries.

D. DEM

This sections defines a so-called “inline” digital elevation model. The recent version of ENVI-met does not support orography, but ENVI-met already holds a number of interfaces to include it in future versions.
