How to couple Lammps with FEA package

Hi

I am trying to solve a crack propagation problem where the crack region belongs to continuum region and also to the atomistic region. I am wondering is there any way I can model this in Lammps? What is the procedure of invoking a FE software like ANSYS from Lammps? I will be very grateful if you suggest me some materials on how to couple Lammps with FEA packages.

I appreciate you help.

See Section 6.10 of the manual. LAMMPS can be
built and used as a library, so it can be used with
other codes. People have done this for various finite
element codes. E.g. see the AtC package which is
included with LAMMPS. But there is no magic bullet
here. You have to figure out how to do it with the
other code and in this case know the internals of ANSYS
and how to modify it to work with LAMMPS.
