## Namelist "External_Force"

This data set is used to define an external force that steers the flow. Otherwise, it can be omitted.

## Full data set of the namelist

## Definition of the data set

### Force_Option_I_Direction

• Type : Integer value
• This option selects the type of force on the I-component of the force vector.
• 0 : the force component is zero
• 1 : the force component is constant
• 2 : the force component is time dependent and depends on the mass flowrate (special case used for the simulation of a channel flow with periodical boundary conditions).
• 3 : the force component is time dependent and depends on both mass flowrate and wall friction (special case used for the simulation of a channel flow with periodical boundary conditions).
• Default value = 0

### Force_Option_J_Direction

• Type : Integer value
• This option selects the type of force on the J-component of the force vector (see above).
• Default value = 0

### Force_Option_K_Direction

• Type : Integer value
• This option selects the type of force on the J-component of the force vector (see above).
• Default value = 0

### Force_Reference_Value_I_Direction

• Type : Real value
• Reference value of the force component along the I-direction.
• Default value = 0.0

### Force_Reference_Value_J_Direction

• Type : Real value
• Reference value of the force component along the J-direction.
• Default value = 0.0

### Force_Reference_Value_K_Direction

• Type : Real value
• Reference value of the force component along the K-direction.
• Default value = 0.0
