The second update of Flownex® SE for 2020 further expands the possibilities of simulating real-world systems.
Exciting features for this update are a reworked deep solver coupling with Ansys Mechanical for explicit transient co-simulation and automated Nuclear Reactor building script along with many minor enhancements described below.
Ansys Mechanical Coupling
Nuclear Reactor Builder Scripts
Script Generated Reactor Results
Results in tabular form corresponding to the grid layout of the generated reactor network are written to a text file in the ScriptResults subfolder of the project folder. The tabular results are reported at the end of a steady state run as well as during user specified times and at the end of transient runs. A feature is provided to specify output variables that are reported at every time step. These results are written to a comma separated values (csv) file as a time series residing in the ScriptResults subfolder.
Reactor Generation Script
Various improvements were made to the geometric parameter calculations. Network topology generation for the transitions between different types of reactor zones was extended.
The “Description”, “Minimum” and “Maximum” values have been added to the imported FMU variables. The description will be displayed if it is not blank. Minimum and maximum values will be displayed if they are specified in the FMU and the “Display variable information” property is turned on. A warning is given if the minimum or maximum values for inputs are exceeded.
The License modules selection have been updated so that it can work for users that do not have write access to their ProgramData folders.
- Functions to retrieve minimum and maximum temperatures and pressures, as well as critical temperatures and pressures from two-phase fluids via Scripts have been added.
- Added the ability for Scripts to properly work with lists and Snaps – functions were added that get called in the Script before and after loading and saving Snaps. This gives users flexibility to implement their own Snap saving and loading code.
Composite Heat Transfer Component
The “Area multiplication factor” input for the Composite Heat Transfer (CHT) component has been moved to a separate category to indicate that the input is applied to all surfaces.
