ogs5 -- Dual-porosity -- DUAL_RICHARDS -- Multiple Materials

Dear ogs users,

I want to model water flow and mass transport in a dual-porosity 2d domain using ogs5 and DUAL_RICHARDS flow.

I set up a simple model similar to the benchmark “H_us/dual_van” from the 2012 benchmark book “THMC processes in fractured porous media”/chapter 6.2. with one material property bloc for the matrix , one for the fracture (*.mmp file, 1. example see below). It works.

However, my real model domain contains three materials which you usually define in the *.mmp file when using single RICHARDS_FLOW (2. example see below).

My Question: How do you define the matrix and the fracture part for all three materials? Is that possible at all? Just putting all material blocs twice (alternating matrix/fracture and/or all matrix then all fracture) did not work (see example 3./4.).

Hi Johannes,

  the materials have to be present in the mesh, i.e. you have to assign the materials to the corresponding parts of the mesh (material properties are assigned to the elements). Please have a look how the mesh file looks in the H_us/dual_van benchmark.

CU, Georg

Hello Georg,

material ID’s in the dual_van.msh are all the same. In case of DUAL_RICHARDS, you do not add material IDs in the mesh file for matrix and fracture this is just defined in the *.mmp file.

In my single RICHARDS_FLOW model, I assigned all three materials in the mesh file, of course. Now it is a question how to define matrix and fracture part for all three materials.

Best,

Hi Johannes,

  the materials have to be present in the mesh, i.e. you have to

assign the materials to the corresponding parts of the mesh
(material properties are assigned to the elements). Please have a
look how the mesh file looks in the H_us/dual_van benchmark.

CU, Georg

Dear ogs users,

      I want to model water flow and mass transport in a 

dual-porosity 2d domain using ogs5 and DUAL_RICHARDS flow.

      I set up a simple model similar to the benchmark

“H_us/dual_van” from the 2012 benchmark book “THMC processes
in fractured porous media”/chapter 6.2. with one material
property bloc for the matrix , one for the fracture (*.mmp
file, 1. example see below). It works.

      However, my real model domain contains three materials

which you usually define in the *.mmp file when using single
RICHARDS_FLOW (2. example see below).

      My Question: How do you define the matrix and the fracture

part for all three materials? Is that possible at all? Just
putting all material blocs twice (alternating matrix/fracture
and/or all matrix then all fracture) did not work (see example
3./4.).
