Ansys FLUENT archive containing the solution files for vortex-induced vibration of elastically mounted circular cylinder. File contains data for different damping ratios. Open it using Ansys Workbench version 18 or later.

This contains all input files needed to run MK-analysis presented in the paper. This example applies for alfa=0.5 and fii=90 degrees, see paper for details. For different stress states or principal stress direction respective values in the *.for file need to be changed. MASTER.inp - Abaqus input file that is runned. Equation.inp - Called by MASTER.inp. Contains linear constraint equations that constrain each boundary node based on the nodal displacement on the opposite edge and phantom node displacement. NODES.inp - Called by MASTER.inp. Gives the nodal coordinates of the unit cell model. vdisp-NODES-imp.for - Example user defined loading file called by Abaqus along with MASTER.inp.

Data belonging to the paper: Available analytical formulations compared with FE-3D analyses of asymmetrically imperfect ring-stiffened cylinders under hydrostatic pressure by J.J. Reijmers, D. Stapersma, M.L. Kaminski, C.L. Walters. The purpose of the data is to collect the biases between analytical methods and numerical calculations. The data consists of tables containing analytical solutions and FE results giving the bias for twelve pressure hull geometries. A condensed overview is presented in the paper.

The DeRisk database is an extensive database of long-crested (2D) nonlinear wave kinematics for computation of extreme loads on offshore structures. The database was produced by running the nonlinear potential flow model OceanWave3D [1] on a gently sloping domain. The performed computations spanned a large parameter space, defined by nondimensional water depth, significant wave height and spectral peak period. A work containing a thorough description and validation of the current computations and of the database concept is currently under preparation [2]. The DataBase is openly accessible under the conditions of the present license. Routines for interacting with the database, and usage examples are located at:https://gitlab.windenergy.dtu.dk/fabpi/deriskdatabase.git [1] Engsig-Karup, Allan Peter, Harry B.
