Dear Hua,

as I know from Wenqing, output is in X and Y for H2M, even if you use X-Z-section. Maybe it's the same for Richards flow.

------------------------------------

There is another shortcoming in OGS5 for output 2D deformation result.

Here are tips:

*Telplot: Whichever a coordinate system is chosen for 2D plane strain deformation analysis, i.e. (x, y, 0) or (x, 0, z), the output for this problem always uses x and y coordinates. In that way, the results of a 2D deformation problems are ux, uy; strain_xx, strain_yy, strain_xy; stress_xx, , stress_yy, , stress_zz (off-plane direction), stress_xy.

*PVD of Paraview: Displacements are stick to coordinates in the manner:

(x, y, 0) makes output of ux and uy while (x, 0, z) makes output of ux and uz. Strain and stress are 'strain_xx, strain_yy, strain_xy; stress_xx, , stress_yy, , stress_zz (off-plane direction), stress_xy'.

Therefore, I suggest to use (x, 0, z) coordinates for your 2D example, and check the result of uz according to the above description.

--------------------------------

Cheers

Katharina

Dear all

We are currently using Richards-model for one project. Based on some Benchmark-example, e.g. Foryth, we got a very quick start. However, we have also problems as:

1. 2D problem doesn't work if the problem in y-z coordinate system

2. Definition of coordinate system is quite confuse, i.e. 2D problem in x-z section, output of velocity is ux, uy

3. The calculation of velocity is with great uncertainty: in some test cases, we got even vx=vy (???) in the output file.

Does anyone have an idea or experience on the 'RICHARD's flow'?

Dear all,

If you solve THM coupling problem with deactivated domains, please patch your source code with my today's commits , which contain the bug fixing for the boundary condition assignment.
