Hi all,
in addition to the forum I ask here:
In the (first) benchmark book there is in section 10.1.1 a description
of a diffusion benchmark for an axisymmetric setup. Where do I find this
benchmark in the benchmark folder?
/benchmarks/C/diffusion/Diff_HTO_test.xxx is for linear diffusion, or do
I miss something?
Would it be enough to put the $AXISYMMETRY keyword into the msh file?
And...how does this work then? Is 0,0,0 the center of symmetry?
Thanks, Georg

Hi Georg,
yes, setting $AXISYMMETRY keyword into the msh file should be enough. X coordinate given in the mesh corresponds to a radial distance from origin (r=0).
you might be able to get some hints from benchmarks/T/T_1D_axi which is an axisymmetric model for heat transport in a hollow cylinder.
Best,
Nori

Hi Nori,
thanks for the hint...that is what I guessed. I am "only" still a little
bit irritated that the books describes benchmarks which were obviously
removed or never added....That is not good.

it seems the benchmark corresponds to benchmarks/C/diffusion/Diff_HTO_test. You can find a word "radial" in the RFD file. BUT there is no $AXISYMMETRY keyword written in its mesh file, which means OGS simulates it as a 1d problem. I guess someone forgot to add the keyword in the mesh file when current mesh file format was introduced.

Hi Georg,
Nori is right: just put that keyword at beginning of mesh file. One thing, elem->getVolume() for symmetrical element returns area of 2D cross section. Bastian will fix the volume calculation for symmetrical elements. The current volume calculation does affect the correction of results.

Hi Wenqing,
your remark on the symmetric elements I do not completely understand. I
would like to use a 1D setup with linear elements. I guess that linear
elements are symmetrical, or?
I know I also use elem->getVolume() in the OGS-GEM coupling for
calculation of "node volumes"....I guess that would give now wrong
results, correct?
I guess it would be more save to create a 2d triangle mesh that
aproximates a segment of circle, or?

Hi Georg,
For 1D element with asymmetrical assumption, the return value of elem->getVolume() should multiplied with 2*pi*r in the current version. You can try to correct 1D of that in elem-> computeVolume() while remove if(axisymmetry) conditions in calcLumpedMass() for your test.
For your case, 1D or 2D dose not matter except the correct volume calculation, if which is needed somewhere else.

Wenqing

Hi Georg,
I have implemented the volume correction in my branche version. I am not sure yet how long it will take to get it back to the trunk version.
Do you need the volume correction?

Hoi Bastian,
I guess I will need it. I am currently setting up a correct test
example, as for the HTO benchmark the setup and the description do not
agree...
Please just tell me in which branch (and which files) you implemented
the volume correction 
Thanks, Georg
