Interfaces 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 1 layer model with a flat surface and a flat interface file.

Example interfaces.txt¶

# number of interfaces
1
#
# We describe each interface below, structured as a 2D-grid, with several parameters :
# number of points along XI and ETA, minimal XI ETA coordinates
# and spacing between points which must be constant.
# Then the records contain the Z coordinates of the NXI x NETA points.
#
# interface number 1 (topography, top of the mesh)
.true. 2 2 0.0 0.0 1000.0 1000.0
path/to/interface1.txt
#
# for each layer, we give the number of spectral elements in the vertical direction
#
# layer number 1 (top layer)
16

Here the simplest case of an interface file is show:
