The GAMM Committee for Numerical tools in Fluid Mechanics organizes workshops which should still assemble specialists of a slender box of computational fluid dynamics (CFD) to replace rules and studies to be able to speed-up the advance during this box. during this feel it was once advised workshop should still deal with the answer of CFD difficulties on vector desktops. hence we equipped a workshop with the identify "The effective use of vector desktops with emphasis on computational fluid dynamics". The workshop came about on the Computing Centre of the collage of Karlsruhe, March 13-15,1985. The participation have been constrained to 22 humans of seven international locations. 18 papers were provided. within the statement of the workshop we wrote: "Fluid mechanics has actively motivated the improvement of superfast vector pcs just like the CRAY's or CYBER 205. Now those desktops on their flip stimulate the advance of latest algorithms which lead to a excessive measure of vectorization (sca1ar/vectorized execution-time). yet with 3-D difficulties we quick succeed in the restrict of current vector pcs. If we'd like e.g. to resolve a process of 6 partial differential equations (e.g. for u, v, w, p, ok, € or for the vectors u, curl u) on a 50x50x50 grid we've got 750.000 unknowns and for a 4th order distinction technique now we have circa 60 million nonzero coefficients within the hugely sparse matrix. This characterizes the kind of difficulties which we wish to talk about within the workshop".
