3D Finite Element Modelling
AS Mosley uses ANSYS general purpose finite element package to perform detailed 2D and 3D finite element analysis.
The detailed local finite element model represents the exact geometry and includes all interfaces and boundary conditions. Detailed finite element analysis is performed to investigate the stresses, strains and deflections in a structural model. This is carried out to determine strength and leakage capacities of equipment as well as investigating fatigue characteristics. An example of 3D modelling would be determining the relationship between peak stress and applied load for a subsea wellhead system.
2D and 3D thermal analysis is carried out to determine temperature distributions, stresses, strains and deflections for both conduction and convection heat flow investigations.
Computational Fluid Dynamics (CFD)
CFD is performed using ANSYS CFX to determine fluid velocity and pressure distributions for compressible and incompressible flow. This has been used to assess the presence of vortices and to investigate failures of control lines in subsea equipment. Each aspect of the local finite element analysis can be used to assist the detailed design required for a specific product development.
