Welcome to Icarus Simulation!

Based on the academic work in computational mathematics by Prof Claes Johnson together with former student and now coworker Dr Johan Jansson, Icarus Simulation AB offers services in

  • advanced computational simulation: unique adaptive finite element technology
  • courses on mathematics and simulation technology

State-of-the-art aerodynamics simulation

The work by Johan Jansson is crowned by the leading edge computations presented at High-Lift Prediction Workshop III allowing for the first time computational simulation of full time-dependent turbulent flow around a jumbo-jet in full landing configuration, including the following unique features:

  • automatic turbulence simulation
  • automatic adaptive error control
  • computational efficiency
  • superb agreement with experiment including stall

The flow simulator by Jansson opens the possibility of predicting the performance of new designs and constructing a first real flight simulator based on the real physics of turbulent air flow. Such a simulator will open to new forms of realistic pilot training of e.g. take-off and landing of a jumbo-jet under severe wind conditions or machine failure.
