Basic Information
Name of Program
FD2MOD
Version-Date
July 1996
Description-Date
July 1996
Catchwords
utility program
finite differences
modifying the difference of two topographies
Short Description of Functionality
With the program fd2mod you can modify the difference between two finite difference topographies dtopo.dat in various ways. dtopo.dat is a result of the program fd2del. The result of fd2mod can be used as input for fd2del again.
Input-Files
- (req) general input data (filetype fd2mod.dat)
- (req) difference of two finite difference topographies which should be modified (filetype dtopo.dat)
Output-Files
modified difference of two finite difference topographies (filetype dtopo.dat)
Methodology
In addition to program fd2del an specified area of the difference of two finite difference topographies ZD is modified according to the following rules:
- 7: ZD(i) = ZD(i) + MODWERT (add a constant value)
- 8: ZD(i) = MODWERT (give a constant value)
- 9: ZD(i) = ZD(i) + ZD(i) * MODWERT/100. (add a percentage of the original value)
- 10: ZD(i) = ZD(i) + MODWERT or ZD(i) = 0.0 (add a constant value, but don't deepen the original topography)
