there was no interest in using them and the maintainance burden grew pretty large as the Dumux and eWoms code-bases continued to diverge.

\eWoms provides two sorts of models: Models which use a fully-implicit
|
|
discretization in space and time and models that use a
|
|
semi-implicit space and an explicit time discretization.
|
|
|
|
Fully-implicit models as implemented by \eWoms describe the
|
|
conservation quantities of a flow system as a system of strongly
|
|
coupled partial differential equations which is directly using a
|
|
non-linear solver. Physically, these conservation quantities are mass,
|
|
momentum and energy; Although the momentum is usually not explicitly
|
|
conserved in the context of flow models for porous media.
|
|
|
|
In section \ref{box} a short introduction to the vertex centered
|
|
finite volume scheme (VCFV or box method) used by \eWoms as the
|
|
primary spatial discretization is given.
|
|
|
|
The purpose of this chapter is to introduce how flow problems can be
|
|
solved in \eWoms. Being a simple but representative case, an
|
|
isothermal two-phase problem (i.e. two fluid phases, one solid phase)
|
|
will be considered. The source code of these tutorials is shipped with
|
|
the \eWoms source package and can be found in the \texttt{tutorial}
|
|
directory.
