Jan Stránský requested more information:
> time step is set as 1e7. As soon as the simulation starts, the
particles explode and flow out.

it seems like the simulation is unstable = has too large time step. What
is the value of PWaveTimeStep?

Concerning mass reduction, what does "last step" in "the last step is
mass shrinking" mean? At the end of simulation? Now I understand what
you mean, but don't see the point / advantage fro its usage..

As said, any material parameters modifications "to make the simulation
faster" changes the physics. If it is suitable is very individual and
there is no general answer if it is good or bad.

cheers
Jan
