Benchmark problems

The benchmark organization had been considered to improve the exchange of information between the different teams working for the coordinated research program and to make conspicuous the needs of improved calculation tools based on refined analytical methods. Three groups of benchmarks had been proposed: the first group was decided at the Swierk (Poland) Coordination Meeting of the program (1973). This group of problems is based on one dimensional transport problems. It is composed of four problems that are named Swierk 1 to 4. The results of these benchmarks has been reviewed at the Bologna (Italy) meeting (1973). The second group of benchmarks was proposed after the Bologna meeting. Two benchmarks related to two-dimensional assembly-problems had been proposed by France and are named CEA 1 and 2. Two other benchmarks treat rectangular two-dimensional geometry and were provided by Switzerland; they are named EIR 1 and 2. These benchmarks were reviewed for the first time at the Paris meeting in 1977 but the results were not sufficient to render a final conclusion. A second review was done at Lugano in 1978 and definite conclusions were obtained. The detailed test of all these benchmarks is given in Annex
