VMA - Finite Element Analysis for Ship Structural Design


listed in alphabetical order!

Maestro	An integrated ship structural modeling, analysis, and optimization system. Maestro combines rapid ship-oriented ship structural modeling, large scale global and fine mesh finite element analysis, structural failure evaluation, and structural optimization in an integrated yet modular software package. Maestro’s core capabilities represent a system for rationally-based optimum design of large, complex thin-walled structures.

Nauticus Hull	Nauticus Hull is a complete software system for ship design and strength analysisfrom Det Norske Veritas.

Poseidon	Poseidon is designed to be used by shipyards, owners and design bureaus. The integrated environment helps to cut the time for the structural design and assessment to a minimum. Main features; easy and flexible structure definition of hull cross sections, automatic generation of 3D structural arrangement, rule based determination of scantlings, no restrictions with respect to ship type, automatic generation of FE-model and loads in 2D and 3D, direct calculations, assessment of deformations, ultimate strength, fatigue, natural frequencie...

Safehull	The ABS SafeHull System is a revolutionary new approach to the evaluation of ship design based on dynamic analysis. It is based on thorough and easy-to-apply engineering analysis techniques, leading to improved reliability and enhanced safety of ship structures. SafeHull criteria has been adopted as a condition for ABS Classification and Rule Requirement for tankers, bulk carriers and container carriers.

Shipright	Shipright uses finite element methods in assessing both the overall and detailed structural capability to withstand static and dynamic loadings assessment of operational considerations such as structural capability to withstand dynamic loadings from partially filled tanks, or the influence of thermal loadings.

StabCad	StabCAD for Floating Stability Analysis is improving the way that engineering problems are modeled and solved. Using the power of graphics, the designer can move from a conceptual sketch to a working model without the intermediate step of joint and element layout and numbering. Vessel configurations and wind areas are also defined graphically with the powerful CAD features of the PreStab graphics preprocessor.

Stahl	Stahl is a tool for calculating hull structure assessment under dynamic loads. This code integrates the seakeeping calculated dynamic loads into the ship's structural design procedure. This approach enables an adequate representation of ship structures, and realistic assumption on loads combination. Structural module is based on a F.E. package suitable for preliminary structural design, while the seakeeping module is based on a linear strip theory code integrated with a statistic processor.

StruCad 3D	StruCAD 3D is a 3D software package for the structural analysis and design of steel and concrete structures. Some Features and Capabilities are: Members with variable cross sections, Elastic supports, Permanent settlements, Beam and truss elements, Nonlinear tension only / compression only elements, 3-and 4-node plate elements, 8-and 20-node solid (brick) elements, Automatic wind, wave, & current load generation on structural & nonstructural elements, Automatic tow and inertia load generation due to pitch, roll, and heave Moving load generation and analysis, Wave dynamic response analysis...

Trident	Trident is a comprehensive suite of advanced structural analysis software for naval architecture and marine engineering applications. From designing sounder ship structures to understanding the impact of waves on an offshore platform, trident analysis software provides all the necessary tools for structural design and optimization. Analysis capabilities include linear and non-linear, static and dynamic, natural frequency, buckling, thermal stress and heat transfer.

While	While is a tool for estimating the loads due to underwater explosions. This code evaluate the loads from the pulsations of the gabs bubble originating from underwater explosions. These loads are able to induce whipping, i.e. flexing motion of the whole ship hull in its low frequency vertical vibration modes. The code solves the equations of motion evaluating radius, depth and migration velocity of the gas bubble as a function of time. Starting from these dynamic variables, the loads in terms of fluid acceleration are obtained, following the model assumptions where the fluid is assumed incompressible and irrotational .
