CONVERT: Finite element mesh convert utility.
This application (nearly 10000 lines of code) reads in a three-dimensional finite element mesh with either hexahedral or tetrahedral elements, reconstructs the connectivity information, renumbers the finite elements so to reduce the finite element graph profile, writes output for visualization in different formats, and finally writes out the input data file for the preprocessor modules of both (P)AMPS and (P)BOLTZ packages. CONVERT will be the future consolidation of CONVERT3D, CONVERT2D and CONVERT1D for 3-D, 2-D, and 1-D meshes, respectively.

AMPS3D: Advanced Materials Procesing Simulator 3-D.
Mixed finite element sequential application for advanced materials processing simulation in three-dimensional space. Major features: second-order accurate mixed velocity/discontinuous pressure finite element on tetrahedral and hexahedral element geometries; coupled momentum, energy, induced electric current, and mass concentration balances implemented through Galerkin's weak formulation; non-inertial frame or reference available; flexible boundary conditions; multiple probes for monitoring field variables at any spatial position; consistent novel method for setting a pressure level in confined flows automatically implemented; robust Shamanskii accelerated Newton-Krylov nonlinear solver; portable multi-language FORTRAN/C++ object oriented code; automatic output for EnSight6.2 visualization package; theta-time integration: forward Euler (theta=0), Crank-Nicholson (theta=0.5), and backward Euler (theta=1); gravitational fluctuation (g-jitter) implemented.

SNLSOLVER: Sequential Nonlinear Solver.
Stand-alone sequential solver for large systems of nonlinear algebraic equations resulting from finite element approximations of partial differential equations. High-order convergence rates are obtained with the options: (i) Shamanshii accelerated Newton's method and sparse LU factorization of the Jacobian matrix or (ii) ILUTF preconditioned Krylov-Newton's method with Shamanskii acceleration. The code is multi-language C++/FORTRAN object-oriented in reverse communication with the user's C/C++/FORTRAN code embedded into the C++ main program. This software is particularly useful either to solve large systems of highly nonlinear algebraic equations arising from the discretization of time-dependent/parametrized 2-D partial differential equations or to solve smaller systems resulting from the discretization of 3-D counterparts. SNLSOLVER is embedded in AMPS3D.
