OrcaFlex 11.6: Advanced Offshore Marine Dynamic Analysis Software

OrcaFlex 11.6 is a major release of Orcina’s industry-leading software for the global static and dynamic analysis of offshore marine systems. The latest build is OrcaFlex 11.6d , which is a maintenance update recommended for all users of 11.6a to upgrade to .

Key New Features in the 11.6 Series

Updated Shaded Graphics (DirectX 12 & PBR)

The shaded graphics engine has been completely re-implemented using DirectX 12 with Physically Based Rendering (PBR) . This delivers:

• Advanced lighting models for sea, seabed, and sky with customizable environment drawing .

• Shadows cast by objects based on sun position for enhanced depth and realism .

• Underwater viewpoint simulation accounting for natural light absorption and scattering .

• A new projection mode parameter (perspective or parallel) to maintain viewing angles when switching between wireframe and shaded modes .

Enhanced Frequency Domain Analysis

Taken together, these enhancements represent a significant improvement in functionality :

• Separate Wave-Frequency & Low-Frequency Results: After performing frequency domain analysis at low frequency combined linearisation, users can now choose whether results are reported for the wave frequency solve or the low frequency solve .

• Vessels as Child Objects: Vessels can now be connected as child objects .

• Sea State Disturbance RAOs: Now supported with corresponding environmental results .

• Additional Results: Vessel other damping force and moment results, line drag force results, and Morison element drag force results are now available .

Improved Constraint & Load Specification

• Full 6×6 Matrix Specification: Constraint stiffness and damping loads can now be specified using full 6×6 matrices, allowing non-isotropic models without needing chains of constraints .

• Python Variable Data: Constraint stiffness & damping loads and applied loads can now be specified using Python variable data, enabling forces and moments to be defined directly as bespoke mathematical functions of simulation time and line arc length .

Line & Environment Enhancements

• User-Specified Radius for Stress Results: For line results that depend on radial position (e.g., stress components), users can now request results for an arbitrary radial position (previously only inner, outer, and mid-wall) .

• Nominal Depth Specification: Users can now specify a nominal depth for wave theory calculations and current vertical stretching, decoupling this from the seabed origin .

• External Wireframe Data: Wireframe drawing data for vessels, buoys, and shapes can now be specified in external panel mesh files, reducing file storage requirements and removing vertex/panel limits .

• External 3D Seabed Data: 3D seabed data can now be specified in external files .

View Filters & Customization

Model drawing can now be customized on a per-view basis using view filters that control drawing properties of individual objects or object types. Filters use regular expression pattern matching for fine-grained control and can be exported for reuse .

Line Setup Wizard Generalization

The Line Setup Wizard has been generalized to allow arbitrary line results variables (including user-defined results) to be used as targets, rather than only a limited set of pre-determined variables .

Move Objects Wizard

The Move Objects wizard now allows objects to be rotated around an arbitrary axis, rather than only horizontal plane rotation .

Core Capabilities

OrcaFlex provides comprehensive analysis capabilities for offshore engineering :

• Analysis Types: Nonlinear time domain (implicit & explicit), linear frequency domain (1st & 2nd order), quasi-dynamic, modal, fatigue, VIV, and extreme value statistics.

• Modeling: Fully coupled vessel-line analysis, line-line contact, seabed interaction, P-y soil, line feeding, and coupled wind turbine analysis.

• Automation: Extensive Python API (OrcFxAPI), MATLAB interface, DLL integration, and batch processing.
