Hi,

thanks for the data.
For such case, fitting the strength should not be a problem IMO..

> O.dt = .8*PWaveTimeStep()

this is very sharp dt, consider using a lower value (as your particles overlap a lot, having the effect that their "size" from interaction point of view is actually smaller).
For a computed strength, try to re-simulate it with half and/or quarter dt value to verify if it is correct. If the value would differ significantly, then you should use smaller dt.

just a note, epsSoft should be negative if you want it to have effect

cheers
