The 46th SIMS conference was held in Trondheim, Norway in October 13-14, 2005. The conference was organised by the Norweigian University of Science and Technology (NTNU). The response of the call for papers resulted in a large number of submissions reflecting current trends and developments in modelling and simulation. The papers were selected through a two phase prodedure based first on abstracts and the on draft papers. The program consisted of 40 papers and 4 keynote presentations. More than 60 participants attended the conference.

The plenaries provided insight on sensitivity analysis of differential algebraic equations, testing with hardware in loop and new possibilities in supercomputing. The program contained both theoretical studies and practical applications in industry. Mathematical modelling and numerical methods were applied in various systems. Computer simulation of heat and fluid flow including distributed parameter systems was an important area. Simulation studies were connected to control engineering and process optimisation. The main applications were in oil and gas industry, energy sector, biological and environmental engineering and mechanical engineering. New features of programming tools and model portability issues were also handled.

A change of the bylaws to include Iceland was approved in the annual meeting of SIMS. The change is now binding.
