Idealized Channel Problem
This example tests ADCIRC version 55 (and beyond). It tests the simulation of a diurnal tide on a sloping beach with a channel along its centerline (adapted from). It tests lateral periodic boundary conditions and the absorption-generation sponge layer. The test finishes in about 8 minutes in parallel ADCIRC (2 processors) for 6 hours of simulation. Find the test at the GitHub test suite.
The mesh is comprised of 64,415 vertices and 127,784 triangular elements, with resolution in the 10-60 m range. The mesh is symmetrical in the east-west direction so that the east and west lateral boundary vertices match for the application of the periodic lateral boundary conditions. An elevation specified boundary condition and absorption-generation sponge layer is prescribed at the southern end of the domain.
IM= 111112: Uses the explicit scheme (computational time step is 2 seconds).
A00, B00, C00= 0.0, 1.0, 0.0: Must be used with explicit scheme.
NOUTGE= 5: Outputs the global elevations into a netCDF4 fort.63 file.
NOUTGV= 5: Outputs the global velocities into a netCDF4 fort.64 file.
NOUTGM= 5: Outputs the global meteorology into a netCDF4 fort.73 file (pressure) and a netCDF4 fort.74 file (velocity).
- sponge_generator_layer: Applies a sponge layer to absorb outgoing waves while generating incoming waves. In this case incoming diurnal tidal waves are generated using the fort.53001 and fort.54001 input files.
IBTYPE=94: Node pairs are matched along opposite lateral boundaries where a periodic (repeating) boundary condition is applied.
