Sigma-X distributes, supports and develops finite element, structural reliability and geotechnical software for the structural and offshore oil & gas engineering industries.

STRAP developed by Atir Engineering Software is one of the UK's most popular and productive structural engineering programs.

STRAP has been used to design the World's most prestigious structures from Dartford to Portugal, from Riyadh to Hong Kong

STRAP is suitable for frames, towers, tanks, bridges, domes and just about any elastic structure.

Design in RC and steel to most codes. Sophisticated dynamic analysis options.

Find out now why it is the No.1 choice of Engineers Worldwide and was used for the design of the London 2012 main stadium

Structural analysis, design, detailing, scheduling and drawing in one easy-to-use, cost-effective package.

The latest version which is fully EuroCode compliant links to Autodesk Revit, uses super fast 64 bit technology and has a new low cost finite element analysis option.

Geotechnical software GEO5 developed by Fine Civil Engineering Software is a very user friendly but powerful tool for solving geotechnical problems based on traditional analytical and finite element methods.

The package consists of individual programs with a unified, user-friendly interface. Each program is used to analyse a different geotechnical task, however the modules communicate with each other to form an integrated suite.

GEO5 software coupled with Sigma-X Support provide you with solutions for stability analysis, excavation design, retaining wall design, foundation design, soil settlement analysis, digital terrain model and geotechnical finite element modelling.

In addition to distributing and supporting STRAP and GEO5 Sigma-X is developing innovative computational mechanical software targeted at the oil & gas industry.

The analysis engine at the core of the Sigma-X Subsea Suite is Sigma-X FE SRA Solver which is being developed to perform deterministic (FE) and/or fast stochastic (FE & SRA) analyses on structures including subsea structures such as pipelines, flowlines and risers.  By virtue of the way the Sigma-X FE SRA Solver is being programmed it will also be capable of preforming stability analyses on floating structures. Functional testing of the first program in the Sigma-X Subsea Suite of software Sigma-X Subsea Pipeline commenced in Autumn 2014. Sigma-X Subsea Pipeline will be targeted at the subsea pipeline analysis and design consultancy sector.

Sigma-X are solution partners to Dassault Systems SolidWorks
