Dear users,

MBDyn 1.5.3 is out.  The tarball is available at


The main change is related to handling of nodes and elements exactly in
the order they are input.  This change *should* be harmless, but please
check carefully and report any issue you may encounter.  By design, there
is no means to reproduce the old behavior; the new behavior should be more
intuitive, since it is what one would expect.

The complete changelog is:

MBDyn 1.5.3
	- added forces NetCDF support (Louis Gagnon)
	- added support for modal damping matrix in modal joint db
	- femgen(1) more user friendly (and documented)
    Backward compatibility issues:
	- nodes and elements now handled in strict input order
    Known issues:
	- Schur solver is broken
	- TotalPinJoint inverse dynamics support is broken
	- RTAI and multithread support incompatible
	- module-octave and multithread support incompatible
    Bug fixes:
	- fix multiple statements bug in string drive caller
	- fix (harmless) memory issue in structural mapping force
	- fix integer division bug in aeromodal element

Enjoy!  Sincerely, p.
