3Di is a cloud-based hydrodynamic software. Simulations are run in the cloud.

The basic license is a good start for working with 3Di. On top of the basic license we offer several modules.

Basic license

  • Unlimited number of users
  • 250 calculation hours
  • Access to the Modeller Interface tools
  • Access to the computational core incl. all processes (groundwater, overland flow, sewerage flow)

The license model for 3Di is a bit different than traditional hydrodynamic flood simulation models. Since we offer a solution with a well integrated solver for all domains, we decided to offer this solution to every user.

Note that for building models on your laptop, or analyzing results using the Modeller Interface no license is required.
