Dear OGS developers,
I would like to merge our implementation into the trunk.
The major changes:
-
Coupled THM time controlled excavation.
-
Neglect H initial effect
According to the effective stress concept the balance equation for DEFORMATION process is written as:
(1)
In current OGS it is implemented as the increment from the initial stress state, and has the form:
(2)
where,
is the initial stress tensor,
and 
is the current stress tensor and pore pressure. Apparently the initial state of pore water pressure is not considered. But, sometimes it is necessary, e.g. for coupled HM modelling of excavation process. Thus, we modify the equation to the following form:
(3)
A new sub-keyword is introduced, and users can flexibly choose between Eq.2 and Eq.3.
-
Anisotropic plasticity with Mohr-Coulomb criterion
A benchmark with description in details will be uploaded later.
-
Dependence between storage coefficient and the minimum principal stress
-
Automatically calculate storage coefficient from the stiffness parameters (Young’s modulus, Poisson ratio) of anisotropic material by the coupled LIQUID_FLOW and DEFORMATION modelling.
If there is no objection, I will update the trunk next week. Some benchmarks will be uploaded when the version release is done.
With best regards,
Wenjie

Dear Wenjie,
The changes are great. I only have one suggestion regarding to 2:
Do not allocate the memory or set variable for p_0^w, and directly add \alpha p_0^w I to stress0 as
STRESS0 -= \alpha (S^w*p_0^w + S^g*p_0^g) I.
If you did not do this way, you can skip to apply your change 2 (Neglect H initial effect) because I implemented that addressed above recently.
Best,
Wenqing

I don't quite see in which case these changes make sense. You basically remove the mesh_grid completely when the preprocessor directive is set. I don't see the reason for that because even if you don't need it, it's just a nullptr. On the other hand the missing grid might result in problems elsewhere.
Also, why the new write method?
Finally, please note that what your are always referring to as "shape files" are actually *not* shape files but raster files. For someone working with both types of data/files, using the wrong nameis very confusing.

You introduce a new switch to the cmake file. Why didn't you use the existing OGS_BUILD_UTILITIES?

The reason is that the small tool only involves several classes and does not needs GeoLib at all. Otherwise, there would many unused classes involved in that small tool. The preprocessor is only for that tool.
Also, why the new write method?
There was a writing function to dump mesh into an ogs syntax mesh file before but it was removed. The tool needs it.
Finally, please note that what your are always referring to as "shape files" are actually *not* shape files but raster files. For someone working with both types of data/files, using the wrong nameis very confusing.
Will be changed.

A tool to convert recharge data in raster file to node-wises source for the FEM. Its cmake configuration was standalone before and it was not updated along with the change of mesh classes.

You introduced some preprocessor directives that is only used for *one special case* but makes reading the code *much harder* in general?

Hi Wenqing,
I see your point for introducing the new directive + write method.
However, in the compiled tool there are no "unused classes". Whatever is not needed is not compiled/linked into the final application, so it really makes no sense to re-implement functionality in order to not include GeoLib or FileIO.
Specifically, OGS_BUILD_UTILITIES does not necessarily require Qt.
@TomFischer also makes an excellent point: for this one tool you made parts of the mesh class more difficult to understand. For one thing, there is now the preprocessor directive which makes every instance where the grid-class is mentioned two lines longer. The other thing is that it is not immediately clear what the directive actually means or when it is used/not used.
I would *really* like to urge you to remove the directive again.
As for the write-method: This is basically duplicate code. I would not care if it was inside your tool but as far as I can see it is in the mesh-class itself, which again makes things more confusing because you have to find out which method is called under certain circumstances. So if you absolutely want to keep it, please move it into your utility.
Best,
Karsten

I have the concern that introducing the previous existing directive to other places within the code can break other configurations. For what reason the directive was used before? How can be ensured that using the directive at new, additional places in the code has no side effects?
Nevertheless the use of preprocessor directives make code *much harder* to read.

Removed two pre-processor directives that had added before. Now the accessory tools have to be compiled with two options together:
OGS_BUILD_UTILITIES and any of the FEM options, e.g.
-DOGS_BUILD_UTILITIES=ON -DOGS_FEM=ON
The compilation takes longer time if these options are chosen, but one can get a series useful tools in 'bin' sub-directory of the build directory.
Under Linux, the compilation of ConvertGliToVtk may fail due to missing of library on the system (the error message could be: cannot find -lVtkVis)
