I have given
starting time 0
stopping time 0.0015
time step 0.00001

Thanks for ur responce.

I got the mistake what i did.

I have given the parcel count very less. i e 200.
we need to give for each time step minimum one parcel is required. now i have given 3 laks/sec. so almost 3 drops per time step.

Thanks Pauli..

bye
