3. Enhancements

3.1 GENERAL (IPS)

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.

Figure 1: Example of Search bar added to Components.

Added an improved image selector to styles – a gallery type image selector is now shown if the user chooses an image for a fill style.

(5)

A setting was added to suppress project reloads when file system changes in the project is detected. When a change is detected the source of the change is now displayed in the restart dialog.

Changed drawing pages so that Style and not Style Sheet is used by default. This was done to make it easier to assign background images to pages.

Changed the order of license checks so that a meaningful error message is given. The product not supported error was the error always given no matter what the true error is.

Increased the default page size 16-fold.

Figure 3: Increased page size.

3.2 EXCEL INPUT SHEETS, REPORTS AND PARAMETER TABLES, AND

EXCEL COMPONENT

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.

3.3 SNAPS

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

(6)

Figure 4: Comparing Snap files.

3.4 COMPOUNDS

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.

3.5 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.

(7)

Figure 5: Go to disabler option added to context menu.

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.

Figure 6: Complex Values settings.

3.6 RESULT LAYERS

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

3.7 VISUALIZATION AND GRAPHS

The user is now able to drag and drop any complex value from the property grid to the Phasor Diagram visualisation.

(8)

3.8 UNITS

Added

kg_force/cm

2 unit for pressure, as seen in Figure 7.

Figure 7: Pressure unit added.

3.9 ELECTRICAL LIBRARY SPECIFIC

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 magnetising reactance into account, and

• use the percentage impedance to model it.

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

3.10 SCRIPTS

Scripts can now be encrypted so that proprietary information can be protected when networks/scripts are shared, as seen in Figure 8. Typically, this is used when making libraries of compounds available to other customers.

(9)

Figure 8: Encrypt button available in scripts.

Made double list in mixture properties script of type IPS.Properties.Double in order to allow data transfer to mixture components.

3.11 FLOW SOLVER

3.11.1 Friction Loss Component

Figure 9: 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.

(10)

3.11.2 Motor/Generator Component

Figure 10: 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.

3.11.3 Flow Solver Results

Added maximum time step changes for pressure, enthalpy and concentration in order to quantify severity of transients, as seen in Figure 11.

Figure 11: Maximum time step changes added to Flow Solver results.

Added the Courant–Friedrichs–Lewy (CFL) number as result for both pressure wave and scalar transport to assist with grid size selection, as seen in Figure 11.

(11)

3.11.4 Node

Added convergence and time step changes for pressure, enthalpy and concentration on nodes.

Figure 12: Convergence and Time Step Changes on Nodes.

3.11.5 Pipe

Added a Pressure Iteration variable to the pipe friction factor script so that the script can check the current iteration number.

Added the CFL number as results on pipes for both pressure wave and scalar transport to assist with grid size selection, as seen in Figure 13.

(12)

3.11.6 Warnings and Errors

Added error for cross-sectional heat transfer area being a non-positive number.

3.11.7 Nuclear Reactor

Changed Forward and Backward caption on Secondary Loss dialog for reactor zones to K Forward and K Reverse.

Figure 14: Secondary Loss Coefficients dialog.

3.11.8 Heat Transfer Element

Added Average conductivity and Average cross conductivity results to the Composite Heat Transfer element.

Figure 15: Average conductivity and cross conductivity results added to Composite Heat Transfer element.

(13)

Added Conductivity and Cross Conductivity to sub element results to the Composite Heat Transfer element.

Figure 16: Conductivity and Cross conductivity results added to Sub-Element results. Added Wall/Surface temperature to convection increment results.

(14)

3.11.9 Check Valve

Added the capability to either change the design or the operational condition given a fixed mass flow rate, as seen in Figure 18.

Added the capability to model Check Valves with non-constant opening time by specifying the Opening/Closing dynamic behaviour option as Variable opening/closing time as seen in Figure 18.

Figure 18: Variable opening/closing time option and Change Design options added on Check Valve.

3.11.10 Secondary Loss Components

Added the capability to either change the design or the operational condition given a fixed mass flow rate, as seen in Figure 19.

(15)

Figure 19: Change design or operational condition when a fixed mass flow rate is specified.

3.12 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.

3.13 BUG FIXES

• Fixed the problem where the description of a component could not be written from Parameter Tables.

• Fixed the problem where snap loading deleted formulas in cells on Excel component and Input sheets.

• Fixed the problem where complex double values did not display correctly in XY Graphs.

• Fixed problem where the user had to restart Flownex for changes in the Reactor Neutronics Chart to reflect changes made.

(16)

• Fixed the problem where the Reactivity Table option was always turned on after editing the neutronics chart.

• Check reactor port names before solving – a non-descriptive error was issued, now a descriptive error is issued.

• Fixed the problem where geometrical inputs were not visible on the Composite Heat Transfer component when selecting the “Shell side horizontal tube condensation” heat transfer calculation option.

• Fixed the problem where up and downstream areas are not used correctly for heat transfer when Schedule is selected for a pipe connected to a composite heat transfer component.

• Fixed the problem where New Project commands did not work with API.

• Fixed the problem that prevented network builder being used through the API.
