Dear DuMuX community,
I am trying to set up a poroelastic problem with embedded fractures using
the poroelastic codes as my base codes. A little description of my problem;
my lab has developed strainmeters which have deployed in a field with
series of natural and artificial fractures. The main case we want to make
is that the strainmeters can detect heterogeneities in the field which are
more pronounced during an injection and production episode in the field by
looking at the strain tensor distribution. I want my initial model to
introduce known permeabilities in the field and detect how the strain
tensor behaves in those regions during injection.
I want to start with a sound and simple model which I can build on
consistently and I am seeking your advice and guidance on this problem. In
the meantime, I have been thinking of using the embedded fractures that
were used for the discrete fractures exercise to represent my problem
domain. I am supposed to only change the grid type under properties from
these codes and that will be it? If yes, how do I call the
embedded fracture grid to replace this one?
namespace Dumux::Properties {
// Create new type tag
namespace TTag {
struct TestPoroElastic { using InheritsFrom = std::tuple<PoroElastic,
BoxModel>; };
} // end namespace TTag
// Set the grid type
template<class TypeTag>
struct Grid<TypeTag, TTag::TestPoroElastic> { using type =
Dune::YaspGrid<2>; };
// Set the problem property
template<class TypeTag>
struct Problem<TypeTag, TTag::TestPoroElastic> { using type =
Dumux::PoroElasticProblem<TypeTag>; };
// The fluid phase consists of one constant component
template<class TypeTag>
struct FluidSystem<TypeTag, TTag::TestPoroElastic>
{
using type = Dumux::FluidSystems::OnePLiquid< GetPropType<TypeTag,
Properties::Scalar>,
Dumux::Components::Constant<0, GetPropType<TypeTag, Properties::Scalar>> >;
};
// The spatial parameters property
template<class TypeTag>
struct SpatialParams<TypeTag, TTag::TestPoroElastic>
{
using FS = GetPropType<TypeTag, Properties::FluidSystem>;
using PV = GetPropType<TypeTag, Properties::PrimaryVariables>;
using Indices = typename GetPropType<TypeTag,
Properties::ModelTraits>::Indices;
using type = PoroElasticSpatialParams< GetPropType<TypeTag,
Properties::Scalar>,
GetPropType<TypeTag,
Properties::GridGeometry>,
FS, PV, Indices>;
};
} // end namespace Dumux::Properties
#endif
I apologize for the long email; I am new to DuMuX and figuring out how to
use it to solve my problems.
Thank you so much for your help and advice.
Sincererely,
Henry Arhin.
