Transient iconTransient/Dynamic capabilities

Dynamic simulation gives users the ability to model the time varying behavior of a system. 

The dynamic (transient) simulation features of Flownex include the following:

  • The ability to start the simulation from steady-state or specified initial conditions.
  • Variable time-step sizes.
  • Open loop events can be specified at different time steps (e.g. Varying or fixing of variables; Switching controllers on or off; etc.).
  • Plot values of multiple parameters during transient simulations.


Advantages of Transient Simulation

  • Determine the behavior of plant/system over complete operating range: start up, shut down, accident scenarios.
  • Ensure correct design and material selections that can bring significant savings in plant construction (avoid overly conservative approach).
  • Combination of control and plant thermal hydraulic simulation to identify if the operating problems, e.g. emissions, control philosophy, etc.
  • Effective control strategy can help to save large operational costs (avoid overly conservative approach).
  • Design for and optimize components to ensure optimum system behavior, even during off design and transient behavior.
  • Design and commission control systems using simulations.
  • Dynamic integrated simulations will: Identify bottlenecks, Identify inefficiencies and Identify safety risks not identifiable with steady-state simulation.
