AVEVA Releases Finite Element Analysis Interface for Shipbuilders


CAMBRIDGE, Jan. 14 /PRNewswire-Asianet/ --


    AVEVA (LSE:AVV) announces the release of AVEVA Hull Finite Element

Modeller, a powerful new addition to the AVEVA Marine portfolio which

accelerates and simplifies the stress analysis of ship structures.


    Ship designers rely on the use of Finite Element Analysis (FEA) to ensure

that hull structures comply with rigorous strength criteria and achieve low

levels of vibration for maximum passenger comfort. FEA is a computational

technique for stress and vibration analysis which entails the idealisation of

a physical structure as a mesh of a very large number of small elements.


    Although the analysis itself is a relatively rapid process, translating a

vessel's hull structure into an idealised mesh in such a way as to achieve

accurate and reliable analysis has long been a laborious and time-consuming

process, which is normally repeated several times as the design evolves.

Finally, it is common to include a detailed FEA in an approval submission to

a classification society such as Lloyds Register or Bureau Veritas, in order

to better demonstrate a vessel design's structural soundness.


    Shipbuilding has now become such a rapid process that the FEA cycle

itself can be the critical-path activity. Timescale pressures frequently

require a shipyard to begin steel cutting before final design approval has

been received, so a design change requirement from the classification society

can result in costly construction rework.


    AVEVA Hull Finite Element Modeller has been developed in collaboration

with leading shipbuilders to overcome these problems. It applies

sophisticated, rule-based methods to ensure the rapid idealisation of

structures created in AVEVA Hull Structural Design, to faithfully represent

the essential characteristics of the physical design while ensuring accurate

and computationally-efficient analysis in third-party FEA programs.


    Commenting on this important new release, Stephane Neuveglise, AVEVA's

Product Marketing Manager for AVEVA Marine, said: 'This product meets a

widespread demand in the shipbuilding industry, which must meet stringent

international regulations while faced with severe competitive pressure to

achieve ever lower costs and shorter delivery times.


    'AVEVA engineers have worked closely with our collaboration partners to

develop an extremely powerful and easy-to-use application which is already

meeting or exceeding expectations on a number of different projects. Users

have consistently reported achieving 30-50% reduction in direct man-hours for

FEA, as well as valuable gains in design quality, timescale and avoidance of

construction rework.'


    AVEVA Hull Finite Element Modeller is available for immediate deployment

in an AVEVA Marine environment and may be used effectively on all types of

commercial or naval vessel designs, or other floating structures.

    It is used with AVEVA Hull Structural Design and exports idealised meshes

either in ANSYS(R) APDL format, or in neutral XML format for other

third-party FEA programs. It combines rule-based 'intelligent' idealisation

with extensively user-configurable parameters for the rapid creation of

high-quality meshes. Hull structures may be idealised in their entirety or as

selected blocks, with coarse or fine meshes, enabling rapid analysis in the

early design stages and more detailed analysis of highly-stressed local areas

as the design progresses.
