Flownex includes a feature that allows reactor simulation results to be visualized on a 3D graph, making it easier to analyse spatial property variations within a reactor. To use this functionality, reactor results must first be written to a results file using the reactor results script. A dedicated Reactor 3D Result Script can then extract the stored data and populate a list of tracked simulation results for plotting. Users can display properties such as solid node temperatures, heat generation by TRISO particles, and vertical mass flow on a 3D graph to observe how they vary throughout the reactor. This capability helps with reactor analysis, troubleshooting, and identifying the locations of minimum and maximum values within the model.
