# INITIAL_CONDITION¶

This block links a particular FLOW_CONDITION to the appropriate REGION to define an initial condition. It is set up by first creating a list of flow conditions, and then applying them to appropriate REGIONs.

For example, this block can be used with an hydrostatic condition to set up an equilibrated initialisation, see below.

INITIAL_CONDITION Equilibration
FLOW_CONDITION hydrostatic_pressure
REGION all
