Hi, thanks for the patch - that solves the mode numbering issue.


Kind regards,

	Dear Pierangelo,


	I wanted to check if what I an inconsistency I am observing is
intentional - the behaviour/output of the mode numbers in the .frc files
appears to be different to that of the .mod and input files.


	In my MBDyn input file, if I specify a list of modes to use that
does not begin with 1, for example, 3 modes: list, 3,4,5, I see that
these modes are reflected in the .mod outputs; the id of each modal
unknown is listed as 1.3, 1.4, 1.5... however, this does not appear to
be the case for the .frc files, which seem to restart mode numbering
from 1, i.e. 1.1, 1.2, 1.3.


	Is this intentional? And if so, is there a toggle so that the
behaviour of the .frc mode numbering is the same?

Sounds like a bug.  Please try the attached patch.  Sincerely, p.
