iRIC-FreeBird Update Information

(A non-hydrostatic 3D flow calculation model with a free surface)

We are pleased to announce that FreeBird now supports 3D flow calculations involving porous structures and obstacles (structures with openings).

Key Features of the Update:

Versatile Structure Modeling: The model now handles both overflow and non-overflow type structures.
Complex Geometry Support: You can now analyze 3D flows around objects with complex shapes, including those that allow fluid to pass through them.
Practical Applications: This update enables the simulation of structures containing culverts and other intricate internal passages.

This enhancement significantly expands the scope of 3D flow analysis for diverse engineering and environmental scenarios.
