*DRAGNORM

Data cards :

Either no parameters or an arbitrary number of lines comprising 1 to 20 values each. Note that & can be used if several lines are needed

IGR_1 ... IGR_N

Purpose :

To require that the drag force be computed with the complete velocity modulus and not the projection of the velocity with respect to the line axis.

Details :

Parameter	Description
IGR_1 ... IGR_N	List of lines with drag based on structural velocity

Note

If no parameter is provided, the option is valid for all lines.
