Sesam (structural analysis software)

Sesam is a suite of software applications developed by DNV (Det Norske Veritas) primarily used for structural analysis of ships, offshore structures, and other complex engineering systems. It's designed to perform finite element analysis (FEA) and related simulations to assess the structural integrity, performance, and safety of designs under various loading conditions.

The software suite typically includes modules for pre-processing (model creation and meshing), solver capabilities for static, dynamic, and non-linear analysis, and post-processing (visualization and interpretation of results). Sesam is particularly well-regarded for its capabilities in analyzing complex geometries and simulating environmental loads specific to the maritime and offshore industries, such as wave loads, wind loads, and ice loads.

Key features of Sesam often include:

• Finite Element Analysis (FEA): Providing robust FEA capabilities for accurate stress, strain, and displacement calculations.

• Hydrodynamic Analysis: Integration with hydrodynamic solvers for accurate calculation of wave and current loads on offshore structures and ships.

• Code Checking: Automated code checking against industry standards and regulations to ensure compliance with safety requirements.

• Fatigue Analysis: Tools to assess the fatigue life of structures under cyclic loading conditions.

• Nonlinear Analysis: Capabilities to model material and geometric nonlinearities for more realistic simulations of structural behavior.

Sesam is used by engineers, designers, and researchers involved in the design, construction, and operation of marine and offshore assets. It helps in optimizing structural designs, ensuring safety, and minimizing risks associated with structural failures. The software is frequently employed in projects involving ships, oil and gas platforms, wind turbine foundations, and other large-scale structures exposed to harsh environmental conditions.
