OrcaFlex examples


Below is a list of links to OrcaFlex example topics. Within each topic are a number of examples which each comprise one or more simulation files, a description pdf file, workspace files and sometimes other supporting files. The files for each example are zipped for easy download. The simulation files can be opened and viewed with the demonstration version of OrcaFlex.


L01 Default vessel

In this example we use OrcaWave, the diffraction and radiation solver included with OrcaFlex since version 11.0, to re-create the hydrodynamic data set used by the OrcaFlex default vessel.

L02 OC4 Semi-sub

In this example we use OrcaWave to perform a diffraction analysis of a semi-submersible floating wind turbine platform. This example demonstrates the importance of doing a mesh sensitivity study and explains how to handle the situation where a relatively large superstructure is modelled explicitly in OrcaFlex.

L03 Semi-sub multibody analysis

In this example we take a semi-submersible floating wind turbine platform and divide it into four floating bodies. We use OrcaWave to perform a multibody diffraction analysis of the distributed system. We then use OrcaFlex to perform a dynamic analysis with the pontoons and cross bracings explicitly modelled as line objects.

This example takes advantage of developments made in version 11.4 that improve the workflow when defining external stiffness for multibody models. Therefore, this example and the process described are intended for use with OrcaWave and OrcaFlex version 11.4 onward.
