yes, sometimes / usually DEM is like that :-)

the problem is that with rMean=rRelFuzz, the radius may be arbitrarily
small (you can print the minimal value), making the PWaveTimeStep very
small, too. Thereofore I suggested to change mass only by the smallest
particles (but with manually modified mass, you cannot use PWaveTimeStep
but a "hand made" estimation)

> the last step is mass shrinking, where the mass of all the particles
is gradually decreased to the 1/1000 of the used value. Does it make
sense or do you have good advice?

sorry, I did not get this point at all..

cheers
Jan
