Hello Foamers,

I have a relatively complex geometry consisting of particle packed in a tube. I have everything meshed fine and I run some fluid simulations through the domain. See the figure below to get an idea what I'm talking about:



I would like to intersect a cylindrical slice through the domain so I am left with a cylindrical slice with empty spaces where the particles were in the mesh like the figure below:



Ultimately I would like to be able to get the area of this intersected cylindrical slice in order to build a radial porosity profile through my tube. To make this a little more complicated, I would like the cylindrical slice to be only a quarter of the total circumference.

I am able to do this nicely in GAMBIT, but I now have a polyhedral mesh that I've built in OpenFOAM and of course GAMBIT can't handle such a mesh. Any help is much appreciated.

Dan

No takers on this question?

I would be satisfied with how to operate on the sets and just do the intersection of slice plane Sr with domain D, leaving my slice with empty space. Can i even intersect a 2D plane with a 3D domain (Gambit hates this action by the way)?

Thanks,
