Hi all,
I encountered some problems with setting up a "simple" advective-diffusive Transport problem with LIQUID_FLOW. Maybe someone can help me in finding out what I missed.

Everything is based on a 2D system with a triangular mesh and three domains with different material properties (hydraulic conductivity, tortuosity, porosity).

Starting point is a working configuration that utilizes GROUNDWATER_FLOW. In its simplest configuration I would like to have a diffusive problem only, therefore I set only a constant head boundary on top. Independent form the initial condition, a stationary head distribution will be calculated for the first time step. As expected, darcy fluxes in the domain are very small (around 1e-17 m/s) which gives for practical purposes zero advective transport (compared to diffusion in the domain). Even if I calculate a transient problem the flow solution is not changing....

Now I try to "convert" this problem to LIQUID_FLOW. I replaced all occurrences of GROUNDWATER_FLOW with LIQUID_FLOW and all HEAD with PRESSURE1.
Then I converted hydraulic conductivities to permeabilities, and change the initial and boundary conditions to pressure values instead of head.

Run the stuff -> equation solver does not converge

Is there something else I have to change? Do I have to change the numerical settings (and why)?

Thanks and many greetings, Georg

Hoi Wenqing,
you are right. The hydraulic conductivity in the Groundwater example is wrong. It should be something like 0.1 and then the groundwater example does not work too.
Does that mean that setups that contain two materials with a permeability contrast of 8 orders of magnitude do not work at all? Explicit simulation of fractures as porous media with porosity = 1.0 would then not possible. Correct?
Greetings, Georg

Hoi Norihiro,
I just try to compile Intel MKL which does not seem to work easily on my LINUX box as I have to access the things via our network. It seems I have to pass some PATH options to cmake (although environment variables containing such information are already set).
In any case, I will need this setup to run with the OGS_GEM version and I have to see if I can mix intel MKL and the GEM coupling.
I am currently testing if adding the fracture as line elements "solves" the problem.
Greetings, Georg

Hi,

I've tested the problem with Pardiso solver (a direct solver) in Intel MKL. See attached results (fracture permeability is 4.1e-8 m2).

Georg, the pressure profile looks good but I'm not sure if accuracy of the velocity is enough for you.

Note that OGS has already supported Pardiso but I needed to change one parameter (iparm[12] = 1) to get the accurate results.

Replacing CMakeConfiguration/FindMKL.cmake with an attached one may help you to easily set path to MKL files. With the new cmake script, you just need to set MKL_DIR (a path to MKL root directory) and hopefully it will find all related setting such as include path and library path.

== OpenGeoSys 5.4 (WW) - 2013-03-26 ==
=== Enhancements ===
* Parallel finite element scheme by using PETSc. It works for two-phase flow, Richards flow, heat-transport, liquid flow, groundwater flow. It should work for mass transport with one component. The output are limited to point wise and domain. In present release, the domain output is performed on subdmains with Tecplot with different files, and a single file output will be appeared in the next release. A detailed instruction about how to use this feature can be found [wiki:PETScPage here].
* New mesh partition [https://svn.ufz.de/ogs/browser/trunk/partmesh, ]
=== New parallel benchmarks ===
There are four new [https://svn.ufz.de/ogs/browser/trunk/benchmarks/PETSc, benchmarks ] to test the parallel computing with PETSc, which about two-phase flow, heat transport, liquid flow and Richards flow.
=== New keyword ===
* '''$TECPLOT_ZONE_SHARE''' for output in order to have less verbose Tecplot file. Do not use it if keyword DEACTIVATE is sued.
=== Changes ===
Replace all '''endl''' to '''\n''' in order to avoid flushing buffer on Linux clusters or super computers. Due to this change, [[Color(background-color,red, one who will prepare a new version had better to do this change before committing in order to save conflicts)]].
There are some other changes or big fix that I could not remember in detail.
=== File added ===
mesh_lib_ext.cpp, PETscLinearSolver.cpp/h, findPETSc
=== File removed ===
intrface.cpp/h msh_gen.cpp msh_mat.cpp
=== Benchmark status ===
The following benchmarks do not work
