Engineering Simulation Solutions

CORE MODULES
Flownex core modules include all modules that form the core simulation function of Flownex SE.

FLOWNEX Basic Thermal Fluid Models
This is the basic Flownex steady state version. This configuration includes the ability to deal with both liquids and gasses, the ability to deal with adiabatic flows, as well as flows with heat transfer. The network component models included in the standard version are reservoirs, pipes, ducts, pumps, fans, compressors, turbines, heat exchangers, valves and orifices. This configuration also includes visualization graphs, text outputs, result layers, data logger and result export to Excel, buttons, gauges, sliders, etc. of visualization is included as well as the ability to create compound components.

Advanced fluid thermal module

This configuration includes advanced features such as gas mixtures, homogeneous two phase flow, coupled heat transfer through solid structures, special components used in the design of turbomachinery such as rotating pipes and annulus. It also includes combustion modeling, the Script element and the Excel component.

Design and analysis module

This configuration includes advanced features such as the designer routine, stochastic routines used in probabilistic analyzes (Sensitivity Analysis, Parametric Study). This capability can be applied to all libraries and on both steady state and transient modules.

​

Transient module
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.) and the plot values of multiple parameters are displayed on the screen.

​

Nuclear module
Nuclear models such as the Pebble bed reactor (Generation 2) and advanced pebble bed models (Generation 3). Includes link to RELAP allowing Flownex to communicate and run co-simulations with RELAP.

​

LIBRARY MODULES
Flownex library modules include all modules that include integrated libraries in Flownex SE.

Control module
Control library configuration includes analog components (controllers, Filters, Inputs and outputs IO, math functions and switches ), digital components (Counters, IO's, Logic, Switches and Timers) and some converters (analog to digital, digital to analog, integer to double, etc.).  The Flownex OPC client is used to set up communication of Flownex inputs and results to and from tags in an OPC server.

​

Electrical module
Electrical library configuration includes admittance components (generators, motors, transformers, etc.), auxiliary components (base power, base voltage, synchronizer, etc.), nodes (bus, fixed voltage node, infinite grid, etc.) and switches such as a breaker.

Extendibility
User extendibility allows users to write their own libraries consisting of components, editors, links, solvers, etc. that interface seamlessly with Flownex Simulation Environment. These user extendable libraries can then interact with existing or future Flownex Simulation Environment libraries such as the transient, design and analysis modules.
 
INTEGRATION MODULE
API module
The Flownex SE automation (API) Application Programming Interface provides the functionality to integrate and automate Flownex SE from most existing Windows applications, e.g. Word, Excel, etc. Any application that allows scripting of Component Object Model (COM), Distributed Component Object Model (DCOM) or ActiveX components can now integrate with Flownex SE. The API is also accessible to any .Net aware application. The API module includes an integration to Simulink (Math Works). and includes existing links to other software like EES, MATHCAD and ANSYS enabling the ability to communicate and run co-simulations.
