To specify various parameters relating to the SHEAR7 Slip-Stick Hysteresis module. This keyword is relevant for Shear7 V4.11 and later versions.
Refer to SHEAR7 Data Specification for further information on this feature. For more information, refer to the Shear7 User Guide which is available for download from the Shear7 Support web page.
Several optional lines relating to the Slip-Stick Hysteresis module:
[MODEL_HYSTERESIS=Model Slip-Stick Hysteresis]
[INPUT_FILE=Hysteresis Input File Name]
[TOLERANCE=Convergence Tolerance]
Model Slip-Stick Hysteresis can be NO (the default) or YES. Hysteresis Input File Name can be explicitly specified or left blank, in which case it defaults to the same name as the Flexcom keyword file name, but with a .s7inhyst file extension. Convergence Tolerance defaults to 0.001 if unspecified.

Description |
Model Slip-Stick Hysteresis: |
Select Yes if you would like Shear7 to account for damping from stick-slip hysteresis when calculating the VIV response. |
Hysteresis Input File Name: |
The name of the file containing the input hysteresis curves. If this entry is left blank, the hysteresis file name defaults to the same name as the Flexcom keyword file name, but with a .s7inhyst file extension. If specifying a file name explicitly, do not include any file extension, and this will be added automatically for you. |
Convergence Tolerance: |
The convergence tolerance defaults to 0.001 if unspecified. The iteration convergence tolerance is calculated in Shear7 as the percentage change of the stick-slip damping coefficient. |
