*INFLOW,FILE==path\flow_data.dat

Data format:

One line with 3 values

NBRFLOW NBRCOL ILINFL

Status :

Optional

Purpose :

To take into account the effect of forces induced by internal fluid flow (slugs, ...)

Details :

path\flow_data.dat : file path and name to read the fluid data, the format gives at various step in increasing order, along the riser (arc length in increasing order), the pressure, velocity, and density of the fluid (in an average sense if multi-phase flow). As an option the friction force can be entered as a sixth column as shown below:

Parameter	Description
NBRFLOW	number of the group of elements in which the flow circulates
NBRCOL	NBRCOL = 0 : if friction force not provided NBRCOL = 1 : friction force provided, weight effect is taken only perpendicular to the pipe NBRCOL = 2 : friction force provided but is used if an internal fluid is defined and in that case the internal fluid density is the density provided in the file minus the internal fluid density. weight not included NBRCOL = 3 : same as 1 but all weight included
ILINFL	interpolation flag: interpolation is performed in the datafile to find the value requested by DeepLines; 0 for Lagrange interpolation; 1 for linear interpolation
