2.4.2
Number
of
tracers
NUMBER OF TRACERS = 3
The maximum number of tracers is theoretically 99.
For each of these tracers, the user will have to define the corresponding
properties (see below), the initial conditions (see ), the boundary conditions
(see ) and the injection parameters (see ).
The properties of each tracer are kept in the tracers definition file which
is specified with the keyword TRACERS DEFINITION FILE. This section describes the syntax of this file.

properties
Anywhere in the file, comments can be added by using a ‘#’. All characters
after a ‘#’ will be ignored by ESTEL-2D, therefore if a line starts with a ‘#’, the
whole line will be ignored.
The tracers definition file starts with three lines describing the units, soil
types used in the simulation and then the list of tracers.
‘m’ ‘s’ # space and time units
1 2 3 6 5 4 # list of soils (imat)
[TRAC01] [TRAC02] # list of tracers
The first line defines the space and time units. They need to be identical
to the units defined in the steering file or soil database file. The space unit is
given first inside quotes ‘’’ and the time unit next. If these units are different
from the units from the steering or soil database file, ESTEL-2D will stop the
simulation and will print an error message.
The second line is the list of the different soils used in the simulation. There
should be as many soils as there are soils defined in the soil database, however, the order in which the soils are listed does not matter.
The third line is the list of the different tracers to be used by the transport
module. The syntax for each tracer is [TRACxx] where xx is the tracer number
with a leading zero if necessary. For instance, the name for the first tracer
would be [TRAC01]. The number of tracers should be identical to the number
of tracers defined in the steering file although the order in which they are listed
matters not.
