GfsOutputSolidForce

From Gerris

GfsOutputSolidForce computes the total force and moments exerted by the fluid on the embedded solid boundaries (defined using GfsSolid).

The moments are expressed with the origin of the domain as reference.

The first time GfsOutputSolidForce is called, a description of the different fields is written:

# 1: T (2,3,4): Pressure force (5,6,7): Viscous force (8,9,10): Pressure moment \
(11,12,13): Viscous moment

where the numbers are the column indices and the three components of each term correspond to the x, y and z axis respectively.

The syntax in parameter files is:

[ GfsOutput ]

Examples

• Air-water flow around a Series 60 cargo ship
