In this paper, the authors describe a new graphical environment for learning continuous simulation. This open source software solution enables engineering students to learn and understand various real system models in the CSMP (Continuous Simulation Modeling Programme) language easily, and at the same time learn about the implementation aspects of simulation languages. The software provides efficient tools for creating, storing, and executing continuous system simulation models that are described with differential equations. The graphical block-diagram interface allows students to drag-and-drop predefined modeling blocks, connect them together and create different models of continuous systems.
