A finite element code for subsidence problems: Lagamine
Conclusions A general concept for the numerical modelling of an aquifer subsidence has been presented. Its main advantage is the separation from the three-dimensional flow model (which is a scalar field with one variable per node) and the compaction model (which is a vector field problem coupled to a scalar field problem, with 4 variables per node). This separation is very interesting for a “plate-like aquifer” because the compaction problem is reduced to a series of unidimensional problems with a small number of degree of freedom. The finite element code LAGAMINE has been applied to the flow and compaction problem. The equilibrium equations and the constitutive laws have been developed. Applications are presented in the next papers (papers V and VI). They demonstrate some of the capabilities of numerical simulations with the finite element code LAGAMINE.
