An approach to develop collaborative virtual labs in Modelica

Virtual labs are valuable educational resources in control education, and widely used the process industry as tools for operator training decision aid. In these application domains, virtual typically rely on interactive simulation of large-scale hybrid-DAE models with components different engineering whose description can be greatly simplified by use Modelica language. Existing free commercial libraries domains to describe models. The Interactive library facilitates developing based models, using only Modelica. A new major release is presented this paper, most relevant feature facilitate implementation collaborative written This environment OpenModelica, facilitating cooperative open software. type lab, which allows several students interact cooperatively same model run, an effective tool context learning methods. efficient communication among graphical user interfaces a key issue.
