*CLVIVAD

Data format:

One 1 line with 1 parameter followed by NL lines with 2 parameters each, as follows:

NL
AD(1) CL(1)
AD(2) CL(2)
...
AD(NL) CL(NL)

Status:

Optional.

Restriction:

Used with a modal VIV analysis.

Purpose :

To define a lift coefficient (CL) curve function of the cross-flow amplitude over line diameter ratio (A/D).

Details:

Parameter	Description
NL	Number of lines to read. This is the number of (A/D,CL) couples.
AD(1)	Cross-flow vibration amplitude over line diameter ratio A/D(1)
CL(1)	Lift coefficient CL(1) associated with A/D(1)
...	...
AD(NL)	Cross-flow vibration amplitude over line diameter ratio A/D(NL)
CL(NL)	Lift coefficient CL(NL) associated with A/D(NL)

Note

the curve is multiplied by the curve defined by *CLVIVRE if defined.
