DSD-INT 2019 RiverLab - Spruyt

  1. 1. Delft Software Days 11 November 2019 Aukje Spruyt
  2. 2. The numerical experimental facility to work together on software and models for river research. For the entire river community. ➢ Share your numerical models and code: build on each other’s knowledge and experience ➢ Use the new Delft3D FM Suite ➢ Discuss your issues on the RiverLab forum ➢ Meet your peers on the 'Bring-Your-Own-Model' days ➢ Available via https://oss.deltares.nl/web/riverlab-models/ The RiverLab
  3. 3. RiverLab - ingredients Software • Utilizing the Delft3D FM Suite: • multi-dimensional (1D-2D-3D) • coupling different modules (morphology, water quality, waves) • parallel computing • interactive modelling • advanced visualization • Python scripting • Based on open source policy: dare-to-share Models • Simple testcases • Realistic river models
  4. 4. RiverLab – software implementation • Basis: D-Flow Flexible Mesh (D-Flow FM) engine for hydrodynamical and morphological simulations on unstructured grids in 1D-2D-3D. • 2D (morphological) functionality is already fully validated and supported • 3D functionality available as beta (not fully validated yet) • Basic functionality for 1D hydrodynamics and morphology added within the RiverLab context
  5. 5. RiverLab – Test cases 1. All new features in the software are tested separately with simple test cases. 2. Results are written down in validation documents 3. Test cases are part of the standard test bench 4. Test cases are downloadable via the platform Bed level at different time steps for a moving shoal with Engelund-Hansen transport formulation (o = D-Flow FM, x = D-Flow 1D (SOBEK 3 transition product).
  6. 6. Using functionalities on a realistic test case 1. Based on an existing SOBEK 3 - model for the Waal 2. Model adapted and input added for morphological simulations 3. Preliminary hydrodynamic and morphological results RiverLab – Simple Waal model
  7. 7. 100 year morphological simulation possible RiverLab – Simple Waal model
  8. 8. Platform The platform is available under: oss.deltares.nl/web/riverlab-models 1. Model schematisations are open access: everyone can download them and use them (via version control). 2. You can adapt the model schematisation for your own use, but if you share it with others it should become publicly available (e.g. via the Riverlab platform) 3. Modeling software (D-Flow FM) is released as open source 4. Aiming for one basic version in the ‘trunk’ and specific versions in separate ‘branches’ 5. Together working on tutorials and documentation.
  9. 9. Community RiverLab is intended for the whole river community: • Developers (software and models) • Researchers (universities, institutes, companies) • Consultants • River managers • Public Platform will eventually be linked to Rivers2Morrow within the the NCR website
  10. 10. Community RiverLab is intended for the whole river community: • Developers (software and models) • Researchers (universities, institutes, companies) • Consultants • River managers • Public
  11. 11. Community RiverLab is intended for the whole river community: • Developers (software and models) • Researchers (universities, institutes, companies) • Consultants • River managers • Public Everyone is encouraged to join!
  12. 12. Bring-Your-Own-Model sessions The idea is: • Everyone has to bring their own model (or idea) • Presentations and discussions • Working on your model with help from others • Participants are enthusiastic
  13. 13. Discussion 1. How to make it a success? • Who needs/wants/should to be involved? • Do we miss certain things? 2. Do you want to share your models? • How can we best arrange this?
  14. 14. Discussion 1. How to speed-up developments? • Hackathon • Sprint sessions • … 2. Function of the webplatform? • Only information? • Active community? Other ideas?
  15. 15. Thank you for your contribution! For more questions: RiverLab Support: RiverLab@deltares.nl
