Purpose

To instruct Flexcom to read vortex-induced vibration (VIV) drag coefficient amplification factors from the results of a Shear7 analysis.

FILE=Full Path of Shear7 Output File

[SET=Element Set Name]

The Shear7 file name is required, and should be specified without extension – Flexcom assumes the file type is .plt. If the full path contains spaces, then it should be enclosed in double quotation marks. The default Element Set Name is all elements in the model. *VIV DRAG can be specified at any stage in a restart cascade; the drag amplification factors will be used in the analysis in which *VIV DRAG is invoked (provided it is a static or quasi-static analysis) and in any subsequent static or quasi-static analysis in the cascade; the data is not used in a dynamic analysis. For the Shear7 data to be meaningfully applied, then the elements in Element Set Name (whether default or user-defined) must form a continuous line of elements.

Table Input

Input:	Description
Shear7 File:	The name of the Shear7 output file. You do not need to include the file extension - Flexcom always searches for a file with the correct extension (.plt). This input is mandatory.
Set Name:	The name of the set that contains the elements whose drag coefficients are to be multiplied by the factors that are read from the Shear7 file. This input is optional. The default is All.
