PhD from Department of Automatic Control, Lund Institute of Technology in 1978 about a new modeling language. Started Dynasim 1992, sold to Dassault Systèmes in 2006. Chief architect for modeling software Dymola. Initiated design of Modelica modeling language in 1996.
Previous experience include: Mogram AB (CEO), Dassault Systèmes (CTO Systems), Dynasim AB (CEO).
Working with Julia since 2015 and with Modia since 2016.
Modia (www.ModiaSim.org) is a set of Julia packages for modeling and simulation of multidomain engineering systems (electrical, 3D mechanical, fluid, etc.). Status and plans of a largely redesigned version of Modia is presented consisting of a new syntax in pure Julia mixing equation with function based modeling (e.g. drive trains + 3D mechanics) and new transformation techniques in order that Modia models can be simulated with the ODE integrators of DifferentialEquations.jl.
