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
