Topography File

Topography files are used to define the surface topography of the mesh. The topography file is a simple text file that describes the topography of every interface in the simulation domain. For example the following topography file describes a simple 2 layer model with a flat surface and a flat interface between the two layers:

Example topography.dat

#
# number of interfaces
#
3
#
# for each interface below, we give the number of points and then x,z for each point
#
#
# interface number 1 (bottom of the mesh)
#
2
0 0
6400 0
#
# interface number 2 (ocean bottom)
#
2
0 2400
6400 2400
#
# interface number 3 (topography, top of the mesh)
#
2
0 4800
6400 4800
#
# for each layer, we give the number of spectral elements in the vertical direction
#
#
# layer number 1 (bottom layer)
#
54
#
# layer number 2 (top layer)
#
54
