Bruno Chareyre proposed the following answer:
Hi Christian.
Your suggestion is possible. It needs to skip clump members when
building the triangulation, and insert clumps as spheres. I don't
foresee big difficulties to implement that.

Another possibilty is the opposite, skip clumps and build the
triangulation only with clump members (precondition: clump members don't
overlap too much). This is almost what would happen now without changing
the code too much (it would only need to explicitely skip clumps in the
triangulation, +1 line of code). Consequence of this: there will be
fluid flow through the clumps... Not good.
However, the tetrahedra inside one clump could be just excluded from the
calculation. The fluid would be computed only in between the clumps. It
would give probably more fluid DOFs than your suggestion and it needs
more implementation. The benefit would be a more realistic model of the
pore space geometry.

Cheers.
Bruno
