The global commercial CFD industry can trace its origins to a small terraced shop in New Malden, a south-westerly suburb of London. It may sound like the birth of a retail empire, rather than a CAE business – but its pretty much true. Let me fill in some details.

blog post:”Sledgehammer CFD” – The Best Approach?
Re-reading my last blog (Beginning at the Beginning …5 Parabolic or Elliptic, Or Somewhere In Between?) a slightly disturbing thought occurred to me. Does the distinction, highlighted in that blog, between parabolic, partially-parabolic, and elliptic solution methods have any real relevance to present day CFD? -
blog post:Beginning at the Beginning … 5 Parabolic or Elliptic? – Or Somewhere In Between?
To complete my recollections of the time when I was working on my PhD at Imperial College during 1969-1972 …First of all, a short theoretical interlude. As CFD theorists know, it is often useful to categorise classes of flow according to the form of the governing equations – as parabolic, hyperbolic, or elliptic. Leaving aside hyperbolic – supersonic – flows – I want to focus on the distinction between parabolic or elliptic flows as applied to low-speed subsonic flows. (more…)
