Technical Paper: Diagnosing models with ill conditioning problems and curing them
Ramaseshan Kannan, senior engineer and software developer at Oasys hosted talks at the prestigious World conference on computational mechanics and ACME UK 2015 about diagnosing models with ill conditional problems and curing them.
In the talk, he presents a procedure for detecting ill conditioning in stiffness matrices arising in structural analysis. This method, which has been implemented in Oasys software GSA, uses examples of real-world structural models and how the tool has been applied and found useful.

Top Government Department Approves Use of GSA 8.7
Oasys are pleased to report that its flagship structural software, GSA 8.7, has been pre-accepted by the Building Department of one of the world’s largest and most densely populated Far Eastern cities. The department has added GSA 8.7 to its list of pre-accepted programs, specifically for static linear analysis and elastic critical load analysis. Engineers are now assured that the programs and their methodologies are pre-approved by the department’s staff, who typically deal with dozens of applications each month. This is a welcome endorsement from the organisation charged with setting and enforcing safety, health and environmental standards for private buildings, and to improve the quality of development in one of the world’s most prominent financial centres.
The features we’ve added to version 8.7 have undoubtedly played a major part in the adoption of GSA in an official capacity. It now supports more steel design codes than ever before, with the recent addition of EN 1993-1-1:2010 Eurocode 3 (SS) and SANS 10162-1:2011, and four more RC slab design codes than previous versions. New footfall analysis codes have also been added. We’ve developed an entirely new Mesh Generation Engine, which produces smaller and better-conditioned meshes, and we’ve made a host of Modal and Seismic Analysis improvements.
Arup Triumphs at RIBA National Awards 2014
The RIBA National Awards are the most rigorously judged awards for architectural excellence, with the winning buildings setting the standard for good architecture, so we are thrilled to congratulate our parent company, Arup, who has been involved in projects that won two awards at this year’s event – the London Aquatics Centre and the redevelopment of King’s Cross Station. We're proud to note that both projects featured Oasys GSA software.
Young researchers in the limelight
Oasys is delighted to be supporting the next generation of structural engineers by sponsoring the 2014 IStructE Young Researchers' Conference in London on 5th March. A highlight of the conference will showcase presentations by 25 of the student delegates, who stand to win a share of a £2000 prize fund.
The Young Researchers' Conference is an annual event which provides a platform for research students to present their work and exchange ideas with their peers, industry leaders and selected members of the Institution. This year's keynote address will be given by Professor Molly Stevens FREng FIMMM FRSC MRPharmS FSB who is recognised nationally and internationally as one of the leading younger innovators in the multidisciplinary field of biomedical engineering.

Robustness and Efficiency in Engineering Modelling’ – A Talk at the Society for Industrial and Applied Mathematics.
On 9th January 2014, Stephen Hendry from Oasys spoke at the annual Society for Industrial and Applied Mathematics (SIAM) meeting regarding ‘Robustness and Efficiency in Engineering Modelling’. The talk was well received by the SIAM members, who appreciate seeing their efforts translated into tools, and it also explored how the features discussed are built into Oasys GSA. Most notably, the GSA features which help engineers detect modelling errors and ways of determining the accuracy of element results.
