SNAC
SNAC (StGermaiN Analysis of Continua) is an updated Lagrangian explicit finite difference code for modeling a finitely deforming elasto-visco-plastic solid in 3D, released under the GNU General Public License.
In SNAC, nodal velocities satisfying a weak-form of the momentum balance are obtained as the nodal solution. SNAC shares a mathematical foundation, and thus major advantages, with a standard finite element method (FEM). However, it departs from the FEM by not making explicit use of shape functions.
