 Development focused on developing products which were suitable to nonlinear processes as well as tailor-making nonlinear physical models for this intended use.In the late 2000s, the company started work on building a model library written in Modelica and on integrating models from Modelica with their existing tools.This effort was motivated by needs for more complex models in oil and gas applications and by a desire for model re-use and reducing the time and cost of model synthesis.
