10.7.2 Program System HYD03
The finite element program system HYD03 (Fig. 10.59, right) allows us to analyze three-
dimensional steady-state seepage flow assuming isotropic and anisotropic permeability
accounting for discontinuity systems with user-defined orientations. Piezometric heads,
flow rates and potential seepage surfaces can be introduced as boundary conditions
(Section 10.6.1). Results consisting of piezometric heads, flow rates, hydraulic gradients,
seepage and uplift forces, as well as phreatic and seepage surfaces, can be represented in
various ways (Section 10.6.2).
HYD03 has been used by WBI for more than three decades on a great variety of rock
engineering problems and has been updated several times with respect to computa-
tional efficiency and pre- and post-processing. Modules closely related to FEST03 are
routines for transient seepage flow in porous and double porous media (TRANS and
TRANSDOPO), respectively (Section 6.4.2). TEMP and HYDTEMP are modules for
analyzing stresses and displacements due to temperature changes and heat transfer due
to conduction and convection, respectively, in soil and rock. HYDDIF is a module that
allows the solution of the diffusion equation. Possible applications of this routine are
transient seepage flow and conductive heat transfer in soil and rock, as well as water
uptake in swelling rock. Transient seepage flow driven by density gradients in the water,
induced for example by concentration differences of solved salts in brines, can be ana-
lyzed using the module HYDSALT. GAPOM allows us to analyze gas flow in soil and
rock. The two-phase flow of a gas and a liquid in soil can be analyzed using the module
FLOW2P. GLCOND and COND are modules for analyzing the mass transport of
solid phases such as contaminants in gases and liquids, respectively, in soil and rock. All
the modules listed in Fig. 10.59 (right) allow fully three-dimensional analyses.
A detailed description of the program system HYD03 is given in Wittke (1990) and
Wittke (2000b).
