4.11. Initial Conditions

An initial condition for the DOF of every active equation is required on every block. The Initial Condition block goes in the Fuego Region.

# Fuego Region scope
Begin Initial Condition Block FlowInit
    Volume is block_1
    Pressure   = 0.0
    X_Velocity = 0.0
    Y_Velocity = 0.0
End

There can be multiple Volume is lines within a given block, and you can have more than one Initial Condition block to apply different conditions to different blocks.

If you omit an initial condition for any active equation on any block, Fuego will throw an error telling you which equation is missing and which blocks it is missing on.
