Based on the academic work in computational mathematics by Prof Claes Johnson together with former student and now coworker ass prof Johan Jansson, Icarus Simulation AB offers services in
- advanced computational simulation: unique adaptive finite element technology
- courses on mathematics and simulation technology

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.
This work is presented in edX MOOC courses (edX 1 and edX 2) attracting ten thousands of students and setting a new standard in high performance computing and education.
