New example demonstrating the OrcaFlex interface to SHEAR7

A new example, A06 SHEAR7 interface, is now available on our website. The example illustrates how to access the OrcaFlex interface to SHEAR7, using the steel catenary riser system considered in the A05 Catenary with spar example. SHEAR7 is a third-party program, distributed by AMOG, which performs frequency domain VIV analysis for the purpose of […]

New floating photovoltaic array example

A new example, K06 FPV array, is now available on our website. This example demonstrates one method of modelling a floating photovoltaic (FPV) array system in OrcaFlex and can be found in the K Renewables section of the OrcaFlex examples webpage. The array is made up multiple modular rafts which are connected using indirect constraints […]

IEA 22 MW RWT validation study

We have recently put together a validation study which compares the aeroelastic response of the IEA 22 MW reference wind turbine (RWT) calculated by OrcaFlex, versus OpenFAST (running BeamDyn). A report summarising a full comparison of results can be downloaded from the validation page of the Orcina website. The study considers the structural dynamics of the […]

New diffraction example

A new example is now available on our website: L03 Semi-sub multibody analysis. This example focusses on a semi-sub platform that closely resembles the OC4 platform, as modelled in example L02. In the L02 example, we assume the platform is a single rigid body. In the L03 example, we are interested in the loads acting […]

Correction to L02 OC4 semi-sub example

We have recently identified an issue with the L02 OC4 semi-sub example, where incorrect linear damping coefficients were used as input to the semi-submersible model. To explain the problem, the original damping coefficients were referenced from a comparison study against tank test results, documented as part of the Offshore Code Collaboration study OC6 project – Phase […]
