SimThyr is a free continuous dynamic simulation program for the pituitary-thyroid feedback control system.[1] The open-source program is based on a nonlinear model of thyroid homeostasis.[2][3][4] In addition to simulations in the time domain the software supports various methods of sensitivity analysis. Its simulation engine is multi-threaded and supports multiple processor cores. SimThyr provides a GUI, which allows for visualising time series, modifying constant structure parameters of the feedback loop (e.g. for simulation of certain diseases), storing parameter sets as XML files (referred to as "scenarios" in the software) and exporting results of simulations in various formats that are suitable for statistical software. SimThyr is intended for both educational purposes and in-silico research.[4][5]
