DSD-INT 2022 The visual way of working​ - Joling

  1. 1. The visual way of working Visualization of simulation models through a real-time visual tool Almar Joling 15 november 2022
  2. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 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. 18. Demo time!
  19. 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?
