I am no longer supporting DEFNODE. Upgrade to TDEFNODE.
Here is some help

I am now officially retired and not updating TDEFNODE as often. But I can help with specific issues if you e-mail me at:

TDEFNODE is a time-dependent version of DEFNODE, allowing for analyzing deformation transients as well as block motions.
