AVEVA Finite Element Modeller
Rapid and efficient Finite Element mesh creation direct from AVEVA Hull Structural Design
Shipbuilding is now so rapid that Finite Element Analysis can be a critical-path activity. Accurate hull stress analysis must be carried out quickly and early, so that timely design approval can be achieved; if possible, before ship construction begins. AVEVA Hull Finite Element Modeller accelerates this workflow. It enables automatic creation of efficient Finite Element meshes from AVEVA Hull Structural Design, and data transfer directly into ANSYS Mechanical or other third-party stress analysis programs.
Business Benefits
- Reduce costs
Reduce man-hours for initial finite element mesh creation, or revision following structural design change.
Easier, earlier, quicker analysis enables design simplification, especially on unusual hull designs.
Early design correction avoids costly rework in production.
- Improve quality
The ease of feeding detailed design changes back into the mesh ensures that additional analysis can be carried out later during the design process, ensuring the use of the most accurate and complete hull model.
Easier analysis workflow promotes more thorough design development.
Easier analysis of local, highly-stressed areas enables better quality design.
- Reduce project risk
Begin construction work with increased confidence.
Reduce the risks and contingencies in tackling unconventional designs.
Key Features

Three model views showing the structural panel (right), panel elements (centre) and beam elements (left).
- Save time
Avoid project delays caused by late-emerging design changes and rework.
Reduce contingency planning.
Literature
|
- High productivity
Users have achieved 30–50% man-hour reductions on analysis tasks, and indirect savings through improved design quality and reduced rework.
- Broad applicability
Developed and tested to handle a wide variety of vessel types, including naval frigates, mega-yachts, ferries, container ships and tankers.
- Powerful idealisation
User-configurable, rule-based idealisation techniques 'understand' shipbuilding practice.
Intelligent filtering and simplification enable faithful and computationally-efficient idealisation.
- Easy transfer to analysis
The selected idealisation can be exported as an ANSYS APDL file, or in XML format.
Export the idealised model, the FEM model, or both.
Relevant attributes are transferred, including units system, plate thickness, steel quality, beam cross-sections and moments of inertia, and panel dependency.
- Ease of use
Select model objects to be analysed from a navigation list.
Employ local, global or detailed analysis as required.
Optimised default parameters require little or no adjustment for normal purposes.
Review idealised structure in navigable 3D view.
