eSubsea provide advance engineering services using finite element analysis modelling (FEM). Compare to the structural analysis using beam theory analysis program, the finite element analysis (FEA) gives a better representation of complex structural geometry and local effects using optimised mesh refinement.
eSubsea perform all types of structural analysis and evaluations using the advanced finite element method (FEA) simulation software and program program SolidWorks Simulation by Dassault Systems. Parts or assemblies created in the 3D CAD program SolidWorks can be refined, meshed and analysis using FEA.
The FEA is often complementary to the global structural analysis using SAP2000 where critical areas are identified. Areas with complex geometry or high utilisation are then modelled in Solidworks Simulation for FEA using the correct shape functions and boundary conditions.
The finite element method (FEM) is one of the most important numerical solution methods in a number of problems that can be mathematically described by partial differential equations or integral equations. Finite Element Analyses (FEA), as we know it today, was developed by structural engineers in strength calculations, as a generalization of calculation methods for frame-type constructions, so-called matrix statistics, for two- and three-dimensional problems.
