IDA Simulation Environment a tool for Modelica based end-user application deployment

A new Modelica implementation based on IDA Simulation Environment (IDA SE) is presented. IDA SE is primarily used for development of equation based simulators for end-users with limited modeling skills but provides interesting features also for the advanced user. A recently developed Modelica application for simulation of tunnel ventilation for commuter rail networks illustrates IDA usage. Excerpts of models from this application are presented in some detail as well as a list of present limitations of the IDA based Modelica implementation.
