    55The following example provide a step-by-step tutorial on how to set up a nesting system with one parent (root) domain and two child domains.

    7 1. Prepare parameter files for all domains, e.g. for run with topography and separate topography data for each domain:
     71. Prepare parameter files for all domains, e.g. topography files or static drivers and separate each file for each domain:

    99testrun_p3d (root/parent domain)
    10 testrun_02_p3d (child domain 1)
    11 testrun_03_p3d (child domain 2)

     15testrun_static
     16testrun_static_N02
     17testrun_static_N03

    1619Note that numbering of the child domains must start with "02" as "01" is internally reserved for the root domain.
