Cutoff volume for bubble creation

Dear all,

I am inserting bubbles in a porous structure, which works fine. The only thing, what I am concerning about is, that after some thousand simulation steps small bubbles arise. Their volume (around 0.01) is much smaller than the cutoff volume of 2.0, which is defined in bubbleHistory3D.hh.

This very small bubbles stay in the simulation, which leads to a very long list of bubbles, where only a hand full of bubbles really has been punched. In the resulting vtk- and still-files those bubbles aren’t visible either.

I am therefore wondering, why these small bubbles aren’t automatically cutted of immediately in each simulation step.

Does anyone know an answer to this question?
