Author: willic3

New Revision: 4614

Added:
   short/3D/PyLith/branches/pylith-0.8/pylith3d/libpylith3d/traction_drv.f
Log:
Initial version of driver routine for traction BC.
The driver is being used for consistency with other routines, which have
been designed for the eventual addition of large-deformation versions.
It is also envisioned that this routine will be called from within the
iteration loop, which will also allow for eventually adding large deformations.
