The TRNSYS Simulation Studio serves as a robust, intuitive, graphical front end of the simulation, making the user's job of assembling a detailed system a simple endeavor - similar in nature to hooking up the pipes and wires in a real system. The outputs of one component are graphically connected to the inputs of another. Since its inception of in the mid 1990's, the Simulation Studio has replaced the need to manually edit the text input file.
Users can watch the value of ANY system variable on an online plot as the simulation progresses (any temperature, flow rate, heat transfer etc.). Output devices also allow the user great flexibility in integrating, printing, and reporting any component output value.
