Hi all ,

I want to evaluate the mass flow on a imaginary boundry (this is not a boundry of the case, So this is not a patche)(for example middle of a pipe) by using swak4Foam...Can any one help me??

Sasan.

If the controlSurface is aligned with cell-faces and you have a faceSet or a faceZone the recipe is here: http://openfoamwiki.net/index.php/Co...e_calcMassFlow

If it is not aligned you'll have to define a surface. I believe there are eamples for that in Examples/other/angledDuctImplicit/system/controlDict

thanks for your reply Bernhard,
Can you guide me for creating faceSet or faceZone?? How do I specify the face that I want to evaluate the mass flow on it??

thanks,
Sasan.

FaceSets and faceZones are either:
- created by the mesh converter (for instance the FluentMeshToFoam-converters create them for "internal boundaries")
- you can create them with specialized utilities: setSet or (for newer OF-versions) topoSet

For the usage of these utilities have a look at the tutorials or the swak-Examples (hint: "grep -r" is quite handy for finding scripts that use those)
