*MASSCOEMAR

Data cards :

An arbitrary number of two lines with one value on the first line and up to 20 values on the second line. The second line may be continued using the & character.

coeffmu
IEL1 IEL2 ..

Status :

Optional

Purpose :

To define coefficient to compute marine growth mass and apparent weight. The coefficient coefmu ($\mu$) changes the following parameters for the lines (this corresponds to coefmu=1 in marine growth):

Mass in air: $$ M_{air_MG} = M_{air} + \pi \frac{((OD + 2 * t_{MG})^2 - OD^2)}{4} * \mu * \rho_{MG} $$
Submerged weight:

$$ M_{water_MG} = M_{water} + \pi \frac{((OD + 2 * t_{MG})^2 - OD^2)}{4} * \mu *(\rho_{MG} - \rho_{water}) $$

Details :

Parameter	Description
coefmu	Coefficient. Must be positive, default value is 1.0
IEL1	First element identification number
IEL2 ...	Second element identification number ...

Restrictions :

The selected elements must be previously defined.

Example :

*MASSCOEMAR
2.0
1 - 30

All elements between number 1 and 30 are given an apparent weight of 2.0.

The same definition may be entered with the following syntax :

*MASSCOEMAR
2.0
