*FLOWFIELD, file=$path/filename

Data format:

One line with up to 11 parameters (the first parameter only is compulsory), as follows:

NODE XC YC ZC X1C(1) X1C(2) XC1C(3) X2C(1) X2C(2) X2C(3) X3C(1) X3C(2) X3C(3)

Status:

Optional.

Purpose:

To take an external flow field into account in the calculation of the hydrodynamic loads exerted along the pipe.

Restrictions:

None.

Details :

Parameter Description
NODE_ID The box is centered on node NODE_ID and is defined by the Node frame of reference.
XC, YC, ZC when xc, yc and zc are defined, the box has the same orientation as Node but is centered on (xc,yc,zc)
X1C(1) X3C(3) to define a frame of reference. The box is centered on (xc,yc,zc) , and is given the orientation of the new frame (defined with respect to Node s frame).

Note :

The input file FILENAME used to define the flow field must be a ASCII file with the following format :

Lx Ly Lz nx ny nz nt dt
vx(1,1,1) vy(1,1,1) vz(1,1,1)
vx(2,1,1)) vy(2,1,1) vz(2,1,1)
...
...
...
vx(nx+1,1,1) vy(nx+1,1,1) vz(nx+1,1,1)
vx(1,2,1)) vy(1,2,1) vz(1,2,1)
...

and so on, for a total of (nx+1)(ny+1)(nz+1) + 1 line.
