*CL_CORR,FILE="PATH/CL_CORR_DTB"

Data format:

One line with 1 parameter, followed by one line with 2 parameters, as follows:

RED
IGR_1_ IGR_N

Status:

Optional.

Purpose:

To reduce lift force due to embedment and pipeline movement.

Restriction:

The groups of elements IGR(1) to IGR(N) must have been previously defined.

Details:

Parameter	Description
CL_CORR_DTB	Path and filename of the external data file providing the lift coefficient function of the Keulegan-Carpenter number (KC).
RED	Rreduction coefficient of drag due to pipeline embedment
IGR(1)	Identification number of the first group of elements.
IGR(N)	Identification number of the last group of elements.

Output file format:

The "dhi_param_elem_XX.csv" file has the following format:

Element Number = XX

Time(s)  Kc(-)  Alpha(-)  Cd_corr(-)  Cl_corr(-)
T(1)     Kc(1)  Alpha(1)  Cd_cord(1)  Cl_corr(1)
T(2)     Kc(2)  Alpha(2)  Cd_cord(2)  Cl_corr(2)
T(3)     Kc(3)  Alpha(3)  Cd_cord(3)  Cl_corr(3)
...

External data file format:
