Hi Mithushan,

I think that I may have trouble understanding the problem.

As far as I know your sample code, you use 'regular' spheres, thus particles don't deform. The shape of your cloud deforms under compression.  I expected that you would like to take this deformation into account, and that is why I proposed the tesselation wrapper. If you want to know the volume of the cloud before simulation, you can compute it from its dimensions e.g.
aabbDim()[0]*aabbDim()[1]*aabbDim()[2]

However, I don't think it is the problem, because the tesselation
wrapper would give you the same result (before compression).

Could you try to rephrase the problem?

Karol
