Use cloud project#

This example demonstrates retrieving an existing Flow360 project from the cloud using its unique identifier. It illustrates how to access the project’s geometry, define new simulation parameters (specifically modifying freestream conditions in this instance), and submit a subsequent simulation case associated with this project. This process allows users to build upon existing cloud assets, such as geometries or meshes, for further analysis or parameter variations.

 3my_project = fl.Project.from_cloud("PROJECT_ID_HERE")
 4# Applicable for projects with Geometry being the starting point.
 5geo = my_project.geometry

 7geo.group_faces_by_tag("groupName")

 9# Submit a case with changed freestream velocity and angle of attack

11    far_field_zone = fl.AutomatedFarfield()

Notes#

  • The Project.from_cloud method is used to instantiate a Project object linked to an existing cloud project, identified by its unique ID.

  • Project assets, such as the geometry, can be accessed via attributes like my_project.geometry.

  • Submitting a new case via my_project.run_case utilizes the project structure. Flow360 will attempt to reuse existing compatible assets (e.g., surface or volume meshes) based on the provided SimulationParams, potentially skipping mesh generation steps if suitable assets are found within the project tree.
