The document discusses a visual tool called Digitalys that enhances the visualization and analysis of simulation models used by Royal HaskoningDHV. It aims to improve the communication of model results to stakeholders through interactive features, automated post-processing, and compatibility with various modeling formats. The tool is currently in development to better meet project needs and incorporates feedback from users.
DSD-INT 2022 The visual way of working - Joling
- 1. The visual way of working Visualization of simulation models through a real-time visual tool Almar Joling 15 november 2022
- 2. The visual way of working (VWOW) ◼ In addition to our ‘Digital Way of Working – Increase the quality of our projects by applying automation and digital tooling’ ◼ we want to make reports more than text and graphs – and digital ◼ Animations ◼ Interactive desktop and web tools Stixie D-Stability viewer (https://stixie.royalhaskoningdhv.com), Smart Mooring viewer, 3D Expo (https://www.digitaalmuseumspijk.nl)
- 3. Modelling in a large organization ◼ Royal HaskoningDHV is a large organization (~5800 professionals in 30 countries) ◼ Many modelers on different subjects (coastal, river, urban, industry, …) ◼ Which also use various software from different parties (Deltares, BMT (TUFLOW), DHI) Common flow of processing in such situations
- 4. Why Digitalys ◼ What if we can funnel common workflows through one tool? ◼ Uniform post-processing and reporting ◼ Less scripting and APIs to learn and less version management The flow with Digitalys
- 5. Visually exploring your model results ◼ Often issues with your models can be quickly spot by viewing animated results For example ◼ Boundary conditions ◼ Geometry ◼ Extreme values and dry areas Westerschelde tutorial model (Deltares)
- 6. … but for communication as well ◼ Communicate results with different stakeholders (citizens, lawmakers, etc.) ◼ Easier to understand than ‘technical drawings’ ◼ (Spatial) understanding of the processes involved in your simulation (and its purpose) ◼ Add OpenStreetMap and GIS files to increase recognizability and understanding of model Hurricane MIKE (1990) in DHI MIKE – Royal HaskoningDHV (Olaf Scholl)
- 7. Supported formats ◼ Deltares ◼ SOBEK 2 (ASC & MAP) ◼ Delft3D 4 (‘TRIM’) ◼ Delft3D FM (HIS & MAP) ◼ DELWAQ* / WAQUA* ◼ D-FAST * using short conversion step ◼ DHI MIKE (structured / unstructured) ◼ TUFLOW ◼ 3Di ◼ Infoworks ICM Digitalys will automatically recognize model variables and provide various post-processing options based on availability. Check daily for updates 😉
- 8. A change of perspective ◼ Using orthographic projections, a 3D perspective view can be turned into 2D ◼ …Making it more for suitable for reports 6th generation Maas model Delft3D FM - Deltares – (Aukje Spruyt) Bacton Sand Engine in the UK using Delft3D 4 - Royal HaskoningDHV (Project info – Anne de Beer)
- 9. Feature: Legendary legends ◼ Custom gradients ◼ Legend range clamping ◼ Model grid ◼ Interpolation (average) ◼ Transparency based on value, “no-data” or global alpha ◼ Texturing instead of gradient
- 10. Automatic post-processing ◼ Digitalys recognizes common model variables and suggest additional variables these to the post-processing list ◼ Example: flow magnitude, peak velocity and flowlines are added if the two velocity components are detected (for Delft3D 4, D-Flow FM of Delft3D FM, MIKE ◼ It is also to load an extra model (same grid & timesteps) and subtract values. ◼ However, one could also add additional variables to the NetCDF / dfs2 / dfsu files with scripting and these will also be picked up by Digitalys: And benefit from the analysis and visualizations
- 11. Feature: Flowlines of water and wind velocities ◼ Automatic detection velocity variables ◼ Streamlines can quickly show the direction of water or wind and various model ‘problems’ (e.g. boundary conditions) ◼ Configurable length and lifetime ◼ Integration happens directly on the GPU First: 6th generation Maas model - Deltares (Aukje Spruyt) Second: Westerschelde model - Deltares
- 12. Feature: Interactive analysis ◼ Quickly analyze values through a tooltip or graph over time ◼ Can also export the graph for further processing / reporting Westerschelde tutorial model (Deltares)
- 13. Feature: 3D models ◼ Supports 3D layers of MIKE, Delft3D 4, D-Flow FM of Delft3D FM ◼ Allows interactive slicing of geometry to view the hidden content ◼ Geometry shown above terrain ◼ Still some post-processing improvements to do (3rd dimension complicates various things!) Smooth cutting of geometry - 3D model - Royal HaskoningDHV (Filip Schuurman)
- 14. Feature: River cross-flows ◼ Calculates river cross flow based on the edge of the shipping lanes (provided by shapefile) ◼ User only has to select which river kms are of interest, and wait a couple of seconds ◼ Results are directly exports to CSV and shapefiles Maas model (6th generation) – Deltares (Aukje Spruyt)
- 15. Feature: GIS Export ◼ Exports a complete grid – or selection – with values of a given timestep to a Shapefile ◼ Ready to use in ArcGIS or QGIS (or other tools of choice) ◼ Perfect for additional processing and formatting for maps (e.g. in reports)
- 16. Feature: HIS 1D and processor ◼ Visualization of 1D elements (nodes and segments) from HIS files (and 1D networks) ◼ Statistics post-processor for HIS files ◼ Calculating if model is stable ◼ Returns Excel file with all observation points and the calculated statistics Maas model (6th generation) – Deltares (Aukje Spruyt)
- 17. Video export ◼ Export a video directly to MP4 ◼ All videos in this presentation have been made this way ◼ However, ‘camera’ movement is still a pending feature ◼ Video also allows additional post-processing options Jamuna model (Delft3D 4) – Deltares (Amgad Omer)
- 18. Demo time!
- 19. Wrapping up ◼ Digitalys is a tool to visualize, analyze and post-process various modelling software ◼ Currently in development and in use at Royal HaskoningDHV ◼ ‘Wish driven development’ – By colleagues and project needs ◼ Also interested in your wishes Want to know more?
