High performance computers bring crash simulation times down

According to a Silicon Graphics press release, their servers are delivering record new speeds on a standard 3 car crash simulation using LSTC software. The high performance computing available from several manufacturers makes such simulation more practicable, more realistic, and cheaper. LSTCs LS-DYNA is “a general purpose transient dynamic finite element program capable of simulating…

US “Oil Shockwave” – a simulation or a publicity stunt?

According to Yahoo news, a crisis simulation exercise has found that “Oil Dependence Creates Severe National Security and Economic Risks”. However at least one sponsor of the simulation knew that already. Is this simulation or a publicity stunt? A scenario involving (accodring to Yahoo) simultaneous problems in Nigeria, Alaska and Saudi Arabia, which sent the…

Four practical examples of simulation

Recent posts on this blog have been very theoretical: so here are four good examples of simulation as a useful tool, accepted as part of everyday life: in chemical spill tracking, traffic flow modelling, surgical anaesthesia, and waste water flow. None of these seem at all remarkable to us nowadays; all of them enhance life,…

Is the nature of our attention to signals changing?

OReillys Radar has a post about Linda Stones theory of the changes in the way we pay attention to external inputs (eg telephone calls, emails, meetings, networks, etc.) Highly relevant to our expectations of simulation, and its vocabulary. Linda Stone distinguishes four 20-year cycles: 1945-65: organisation based: pay close attention to anything which serves the…

Games As Political Lessons

A good summary of some recent political games or simulations on WorldChanging. WorldChanging “works from a simple premise: that the tools, models and ideas for building a better future lie all around us. That plenty of people are working on tools for change, but the fields in which they work remain unconnected. That the motive,…

Simulation and our changing culture (and two clever boys)

Yesterday my two sons, aged 8 and 10, raised over £30 for their school by selling CDs of computer games – simple simulations which they had written by themselves – at the school fair. Forgive parental pride: I know there is nothing more boring than the achievements of other peoples children. But it made me…
