28! reading mechanism revised (subdomain/total domain size can vary arbitrarily
29! between current and previous run),
30! former file user_interface.f90 split into one file per subroutine
31!
32! Description:
33! ------------
34! Reading restart data from file(s)
35! Subdomain index limits on file are given by nxl_on_file, etc.
36! Indices nxlc, etc. indicate the range of gridpoints to be mapped from the
37! subdomain on file (f) to the subdomain of the current PE (c). They have been
38! calculated in routine read_3d_binary.
