*FLUMEM

Data format:

A single line with a maximum of 9 values, as follows:

ISU IEXT IINT RHOINT HINT IOP CD IOCD IST

Status :

Optional

Restriction :

A Surface must be previously defined

Purpose :

To define loading on membrane elements

Details:

Parameter	Description
ISU	Surface group number
IEXT	=1 take into account external pressure (0 otherwise)
IINT	=1 take into account internal pressure (0 otherwise)
RHOINT	Internal density
HINT	Height of internal fluid from mean sea level
IOP	if IEXT=1: IOP = 0 unchanged IOP=1 : take into account wave height for external pressure IOP=2: take into account wave height + Froude Krilov forces
CD	If CD>0 a drag force is applied on each wetted surface based on the relative fluide structure velocity perpendicular to the panel. The velocity must be coming towards the structure otherwise the force is 0
IOCD	Option for the velocity used to apply the draf force: 0: current; 1: current- structure; 2: courant+houle-structure
IST	1 to take into account pressure stiffness, 0 otherwise
