Numerical model for simulating shallow water hydrodynamics on the GPU using an Adaptive Mesh Refinment type grid. The model was designed with the goal of simulating inundation (River, Storm surge or tsunami). The model uses a Block Uniform Quadtree approach that runs on the GPU but the adaptive/multi-resolution/AMR is being implemented and not yet operational. The core SWE engine and adaptivity has been inspired and taken from St Venant solver from Basilisk and the CUDA GPU memory model has been inspired by the work from Vacondio _et al._2017)

New Boundary treatment #98

Open CyprienBosserelle opened 11 months ago

CyprienBosserelle commented 11 months ago

Using flux term for new boundary treatment

Proof of concept

[x] New wall bnd for halo flux on GPU
[x] Same for CPU

Implementation

[x] apply wall boundary metafunction designed for AOI wall to model BBox
[x] Implement new segment based bnd
[x] New abs flux for model BBox
[x] Fix Warmstart

Testing

[x] New CI test for wall bnd of AOI
[ ] New CI test for wall of BBox

Docs

[ ] Full documentation page with example
[ ] Demo of stability/instability and if it solves the problem

This is on-hold until testing with new bnd complete
