Hi,


I am thinking about a simulation with clumps and PFV method. I know clumps are not compatible with PFV, yet.
I simulate a sand at microscale and want to have a more realistic grain shape using clumps (maybe 2 or more overlapping members). I see there is the first problem in triangulation algorithm. But it should be possible to use clump center and equivalent radius instead of sphere center and sphere radius for triangulation. I think this is ok as long as clumps are nearly spherical, right?
The next problem is the calculation of fluid volume inside the cells. But isn't it possible to use clump centers and equivalent radius at this stage as well? I know the volumes will not be exactly, but I could live with a small error as long as calculation stays stable...

What do you think about this? Did I miss something, that makes it completely impossible?


Regards,

Christian
