The spacing is generally determined by the interface topography. For example, if you have a flat interface, you can use two points in each direction with spacing equal to the dimensions in each direction. On the other hand, if the interface has a complex topography, the spacing should be small enough to represent the realistic topography. In this case, the number of points will be more. |

The following file is in "specfem3d-master\EXAMPLES\seismoacoustic_bishop2022\DATA_FIG4\meshfem3D_files". I'm curious about "spacing between points which must be constant". How could I determine the correct value of it? Looking forward to hearing from you, I will be grateful !

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
.true. 2 2 652000d0 3493000d0 50.0d0 50.0d0
interface1.dat
interface number 5
.true. 2 2 652000d0 3493000d0 50.0d0 50.0d0
interface2.dat
for each layer, we give the number of spectral elements in the vertical direction
layer number 1 (bottom layer)
18
layer number 5 (top layer)
45
