Abstract.
We present a software package which provides tools for
numerical solutions of elliptic PDE in 3D domain
(boundary value problem). The package is based on two
different unstructured mesh generators. The first is
QMG, written by S.A.Vavasis using octree algorithm
(see S.A.Mitchell, S.A.Vavasis, Quality mesh generation
in three dimensions, In Proc. 8th ACM symp. on
Computational Geometry, 212-221,1992). The second,
AGM^3D  is written by J. Bay and includes a good local
refinement technic (see J. Bey, Tetrahedral grid
refinement, Computing 55, 355-378,1995). The finite
element solver produces piecewise linear approximations
of the solutions.

Some numerical results are given with comments about
the precision of the solutions and the convergence rates.
