To satisfy the specific needs of our clients, the Gsea Design team is developing its own software since 25 years.
Reliability, Innovation and Optimization are the key words which drive us to develop our software.
This way we are today equipped with a full suit of software from material properties homogenization to fluid structure interaction FEA calculation tool.
This suit of software allow us to study an appendage, mast or a boat platform in record time.
This investment was rewarded in 2016 by obtaining the price of high technology from the Nautical Industries Federation for our appendage design tool SOFIA.
Research and development program :
OPHELIA is a stick finite element software. Initially developed in 1986 to design masts for racing boats, we’ve since made it evolve to design any type of slender structure from a multihull float to cargoship masts.
The advantage of a stick model is the gain in calculation and analysis time, allowing to study different configurations quickly without loosing precision or quality of the results.
Here are some features :
Type of calculation :
Today we use OPHELIA to :
RECOGNISED SOFTWARE.
In our project management tooling, we constantly have our finger on the pulse regarding technology, from the most classic through to the most innovative, so as to guarantee the best possible compromise between costs/timeframe.
We run some of our digital simulations using recognised 2D and 3D CAD and FEA software.
HYPERWORKS is a pre / post processing suite, which enables data setting and analysis of finite element models. It’s a multiple solver enabling data setting for different types of solver OPTISTRUC / NX NASTRAN / ABAQUS…
The special feature of this suite is that it is geared towards Optimisation. Once it is coupled with the OPTISTRUCT solver, this tool is capable of providing the optimum stacking for a structure or the optimum form for an opening in a bulkhead.
INSPIRE
Included in the HyperWorks suite, this topological optimisation software quickly pinpoints the optimum structure of simple parts.
FEMAP is a piece of simulation software that provides high performance finite element modelling. This upgradeable software solution for structural calculation in pre / post processing is compatible with the market’s main solvers, including NX Nastran, which is our chosen option.
We also selected this solution as FEMAP is recognised in the sectors of:
(FEMAP provides interactive support to a wide range of solutions from NX Nastran: Linear and non-linear static, clean modes, Eigenvalue, dynamic, frequential response, spectral response, and random response. Furthermore, NX Nastran for FEMAP includes options for aero-elasticity, super-elements, optimisation and DMAP (Direct Matrix Abstraction Program))
For the design of 2D designs, we use AutoCAD LT, the most common CAD software in the world.
From simple definition drawings to ply by bly laminate scheme drawing, our draftmen will comply with your specifications.
We’ve chosen to use the latest version of SOLIDWORKS with its FEA capabilities for the design of our mechanical pieces and for its capacity to run FEA analysis.
We use the Finite Element Analysis (FEA) functionality to calculate the constraints and displacement of parts and assemblies caused by internal and external loads.
To accompagny the diversification of projects we are working on, especially in the industry, we equiped the team in 2020 with the Dassault system suite “3D experience”.
A multi tool platform in a single interface that allows our designers and engineers to work with an optimized flow and within the industry standards.
Our mission : Creating composite parts, which will make a difference tomorrow, both in the marine environment and in industry. Making calculations to ensure our clients the design and fabrication of reliable and innovative composite structures, which perfectly adhere to their needs or ideas, whether they comprise offshore race boats, cruisers or industrial projects.
SOFIA is a software suite for the design of deformable lifting appendages (Foils, Rudders, Daggerboards for the watersports, blades on a wind turbine, etc.) using fluid structure interaction. It is in constant development with a doctor specialized in hydroelastic phenomena and fluid structure interaction in a fluid.
ALAMO is the outcome of tho PhD thesis on composite materials. It allows to calculate the mechanical properties of a composite stacking.
Sandra Is a software to calculate the mechanical properties of hollow sections. These properties can then be sent to OPHELIA to run finite element analysis.
