Flownex SE's update 1 is now available within three months of its latest 2017 release, highlighting Flownex's commitment to paying tremendous attention to regular user-requested updates. 


In this update, attention has been applied to the API, industry requested components and ease of use functionality. 

We continue to lead the way in the systems simulation tool market with a steady hand on quality, reliability and accuracy, timeous dependable support, and frequent user-applicable development.

Workflow Integration | API

A utility function was added to the FlownexSEDotNet class to determine the location of the Flownex executable that is registered with com. 

Added the functionality to list properties so that they can be modified through the API, this includes adding new items to lists and deleting them. Accessing existing items in lists and their sub properties still function like in the past. 

The network builder can now add images to components and background images for pages. 

The network builder can now insert data transfer links. 

The network builder can now call a script in a project. 

Added Python network builder example. 

Workflow Integration

Friction Loss Component

Flow Solver | Friction Loss Component

Added a Friction Loss component that can be connected to a Shaft. This component is typically used to model additional losses and friction on a shaft. 

motor generator component

Motor/Generator | Component

The Motor component that was available in the Electrical library was moved to the Flow Solver library. This component uses a supplied torque speed curve and scaling factor to model the connection of a motor or generator to a shaft. 

Flow Solver Results

Added maximum time step changes for pressure, enthalpy and concentration in order to quantify the severity of transients, as seen in Figure 11. Added the Courant–Friedrichs–Lewy (CFL) number as result for both pressure wave and scalar transport to assist with grid size selection.


Added the capability to compare snap files with each other to the Snaps context menu, as seen in Figure 4. 

search bar

Enhanced Navigation

Added a search bar on top of several windows that will allow the user to quickly filter the items shown. This search bar is present on the component view, data references views and pages view.


Added the capability that a user can click on a component name in Reports, Input sheets, and Parameter Tables and then the user will be taken to the component on the canvas. 

Formulas will not be replaced on cells if it is defined when dragging and dropping onto Excel input sheets. 

Inputs are not prevented from being added to result parameter bindings in Parameter Tables. 


The compound template is now copied together with a compound if the compound is copied to a new project. The template is copied even if a library with the same name as the one in which the compound template was located does not exist in the new project. 

Property Grid

If a property is disabled by a Data Transfer Link, Input Sheet or Parameter Table, the user can see what is disabling that property by right clicking to show the context menu on that property. The context menu will display the item that is disabling the property and will allow the user to go to that item when clicked, as seen in Figure 5. 



Complex values can now be displayed in polar form with the phasor angle in degrees or radians. The user can switch between the cartesian and polar form using the options under the Settings ribbon tab. This setting is used when displaying complex values on the drawing canvas too. 


Added kg_force/cm2 unit for pressure, as seen in Figure 7. 2 


Result Layers

The result layers functionality has been updated to facilitate complex values. 

Compound Components

  • Added a Create Copy option to the compound components context menu as seen in Figure 11. 


Per unit, calculations are removed from the Electrical Library to simplify the user inputs (no base value inputs are required) and results (intermediate values used by the solver are removed). 

The Transformer component is updated to: 

  • • be star/delta or delta/star configured, 
  • • take the core loss resistance and magnetizing reactance into account, and 
  • • use the percentage impedance to model it. 

The Motor is moved from the Electrical library to the Flow Solver library.
