# SOURCE_SINK¶

Specifies coupling between flow condition and a REGION for a source/sink term. It can be used also to define a well.

SOURCE_SINK <source_sink_name>
FLOW_CONDITION <flow_condition_name>
REGION <region_name>
END


Where:

• <source_sink_name>: name of the source_sink coupler.

• <flow_condition_name>: name a flow condition defined in the input deck that will be applied to the region specified in the source sink coupler.

• <region_name>: name of a region defined in the input deck where the flow condition specified in the source sink coupler will be applied.

See example below:

SOURCE_SINK wat_injection
FLOW_CONDITION wat_injector_condition
REGION well_1
