Simulator software is computer software that creates a mathematical model of a real or hypothetical system to observe its behavior under controlled conditions. It is used for training, design evaluation, decision support, and scientific research. The goal is to reproduce essential dynamics while allowing experimentation without real-world risk or cost.

It includes physics-based simulators, discrete-event simulators, agent-based and system-dynamics simulators, and hybrids. They can run in real time for interactive use or in batch mode for heavy computations.

Core features include modeling interfaces, physics engines, visualization, data logging, and optional virtual reality or haptic feedback. Many platforms provide scripting or APIs and support importing external data to extend models or integrate with other tools.

Common domains are aviation (flight simulators), automotive and rail, robotics, telecommunications, energy systems, urban planning, healthcare, and education. Interoperability and model exchange are supported by standards such as FMI. Open-source tools include Gazebo, ns-3, and OpenFOAM; proprietary systems include MATLAB/Simulink, ANSYS, and various commercial simulators for flight, driving, or industrial processes.

Development considerations encompass model calibration and validation, numerical stability, performance optimization, and reproducibility. Users must balance fidelity with computational demands and ensure data quality and provenance.

Historically, simulator software has evolved from hardware-based devices to sophisticated software models that enable safe experimentation, realistic training, and design optimization across industries.
