Output Flux through Boundary Surface
Wenjie Xu
Dear All,
does anybody know how to output the mass flux through a boundary surface in OGS5?
Cheers
Wenjie

You can also use Paraview to slice a plane of your domain and then use a filter called "Surface Flow" (or similar, I don't remember exactly).
Best,
Marc

as Nori said, you can use the TOTAL_FLUX output for fluxes across
surfaces (or polylines in 2D):
#OUTPUT
$PCS_TYPE
HEAT_TRANSPORT
$GEO_TYPE
SURFACE SURF1
$DAT_TYPE
TOTAL_FLUX
$TIM_TYPE
STEPS 1
This works for heat & mass transport, liquid & groundwater flow.
Just set the correct $PCS_TYPE. For some boundary element types (tri,
tet), however, accuracy may not be perfect.
You can also print total heat, or mass stored in your model, e.g. for a
particular material group (MatGroup 0 in this case):
#OUTPUT
$PCS_TYPE
HEAT_TRANSPORT
$DAT_TYPE
CONTENT 0
$TIM_TYPE
STEPS 1
These functions are implemented in the KielTesting branch:
https://svn.ufz.de/svn/ogs/branches/kiel_testing
Jens Olaf Delfs can give you more information, as he implemented these
routines.
Schönen Tag noch, Christof

Dear Xuan,
I suggest to use Paraview for getting a budget through any arbitrary planar surface. You can use the filters like this:
1) 'slice' (define your area where you want to know the flux),
2) if you have a 2d setup add 'linear extrusion' with length of unit 1 into the missing dimension here,
3) 'generate normals' on the new surface,
4) use a 'calculator' filter to compute the flux per node (type 'velocity.normals' to computer a scalar product, both variables should be vectors),
5) and finally 'integrate variables' to get the total flux through the area
Best,
Marc
