Monai and Julia
Monai tutorial with Julia
This is a tutorial realised for BG_Flood on Julia.
Goals
- Check Boundary forcing
- Check wave propagation and runup on complex topography against experimental data
Status

Results
Model behaves similar to other codes and ca reproduce the bulk of the tsunami waves. Results are comparable to the same class of models. The double precision simulation is virtually identical to the Double precision run confirming that in this case there is not much point on using the Double precision.
