Aurel Systems CADSIM Plus v3.4.15: The Dynamic Simulator for Process Safety & Training

Aurel Systems CADSIM Plus v3.4.15 is a comprehensive software platform for dynamic process simulation used to design, analyze, and test industrial processes, with a strong focus on creating high-fidelity Operator Training Simulators (OTS). It enables process engineers and plant managers to build accurate digital twins of chemical plants, refineries, and other continuous processes to train operators, test control strategies, and investigate process upsets in a safe, virtual environment.

Core Function: Real-Time Dynamic Simulation of Industrial Plants
The software’s primary function is to perform rigorous, first-principles dynamic simulation. It solves mass, energy, and component balance equations in real-time to model how a process responds to changes—such as startup, shutdown, feedstock variations, and equipment failures—providing invaluable insights that steady-state simulators cannot.

Key Applications & Features:

1. Operator Training Simulator (OTS) Development

  • High-Fidelity Plant Models: Creates detailed dynamic models of unit operations (reactors, columns, heat exchangers, pumps) that mimic the real plant’s physics and response times.

  • Control System Emulation: Interfaces with or emulates the look and feel of the actual plant Distributed Control System (DCS) or Programmable Logic Controller (PLC), allowing operators to interact with a virtual control panel identical to their workplace.

  • Scenario-Based Training: Enables instructors to launch planned malfunctions, process upsets, and emergency scenarios to train operators on proper response procedures without any risk to personnel or equipment.

2. Process Engineering & Design Support

  • Control System Checkout & FAT: Used to test and validate new or modified control logic (DCS/PLC code) against the dynamic process model before implementation in the live plant, reducing commissioning risks.

  • Process Troubleshooting & Debottlenecking: Engineers can use the model to diagnose historical upsets or explore the impact of potential process changes.

3. Intuitive Graphical Modeling Environment

  • Drag-and-Drop Diagramming: Process flow diagrams (PFDs) are built using a library of pre-built unit operation icons. The graphical diagram is the simulation model.

  • Extensive Thermodynamic & Physical Property Support: Includes robust methods for calculating properties of hydrocarbons, chemicals, and gases.
