In the last hours of 2017, right before the Holidays, the Mimic Development team gave the process industry a big Christmas present. Mimic v3.7.1 is the first Mimic release from the new Emerson Process Simulation Center of Excellence, formerly MYNAH Technologies. This release is packed with capabilities that make the development and maintenance of Lifecycle Dynamic Simulation much easier while, at the same time, improving process model performance. All Mimic users current on Mimic Software Support can download and start using this new release right away.

Mimic Simulation Studio PFD View in Mimic v3.7.1 is a new way of building and viewing Advanced Models. Completely user selectable, Mimic users can continue to use the existing IEC1131 methodology, configure models using PFD view, or even convert existing models from IEC1131 to PFD style. Model execution and functionality remains the same when using IEC1131 or PFD view. PFD View delivers an intuitive and functional way of building dynamic process models including the following advancements:

  • Excellent flowsheet space conservation allowing large process areas on one flowsheet.
  • Process models look like plant P&IDs and PFDs with easily recognizable equipment symbols.
  • Ability to customize equipment and unit ops real-time values per user requirements.
  • Quick drag and drop object-based flowsheets increase the efficiency of model building.
  • Stream View command shows dynamic flows across entire flow sheet in one table, making model tuning quick and intuitive.

Hyper-Fast Model Execution is now available for very fast processes or equipment. In Mimic v3.7.1 model execution threads have been enhanced to include 10, 25, and 50 msec model execution. This fast model execution can be applied to Mimic base models as well as advanced models. This allows users to build dynamic, real-time process models that exhibit the performance of their plant no matter how fast the process dynamics.

More Advanced Modeling Objects and Modeling Functions to make building real-time dynamic simulation in Mimic quicker and easier. The new Objects and Functions include:

  • Pressure Regulator Object designed to maintain a target pressure drop or pressure with VLE balance.
  • Orifice Plate Object designed to reduce the line pressure with VLE balance.
  • Future Value Function Block to compute the future value of a process variable and rate of change with a good signal to noise ratio.
  • PID Reset Functional Block provides reset action that compensates for a variable measurement update time.
  • PID Performance Functional Block can be used in conjunction with a DeltaV ePID block to give the user information about their PID Performance.
  • Joule-Thomson (JT) effect has been added to the outflow from Valves, Pressure Regulators and Orifice Plate objects.

A full list of all the functionality for Mimic v3.7.1 is available at At Emerson’s Process Simulation Center of Excellence, we are committed to make top quartile operational performance attainable to all users across the process industries. Faster, easier Lifecycle Dynamic Simulation with the lowest life cycle costs in the industry is our goal with every Mimic release.
