Is that too much to handle? Or something wrong else. Thanks.

Dear all users,
I was so stupid to forget the error information. Sorry
for wasting your time last time. Sorry. And my problem
as follows.
I am now running a DPD simulation with the following
data. However, 0 step has been done. I totally do not
know what to deal with it now. I have tries some ways
to avoid that happened. I have enlarged the bin to 5.0
which in my opinion is sufficiently a large bin and I also
have decreased the timestep to 0.001 which is a very
small timestep in DPD. Is that too much to handle?
Anyone help me? Thanks inadvance!

Thank you

You lost two atoms at the 0th step, due to bad dynamics. This is why
your simulations stopped before 0th step with error.

If you believe your timestep is small enough and all your pair_coeff,
bond_coeff, angle_coeff, etc are appropriate, then it is most likely
due to overlapping of atoms. Dump atoms and examine them with your
favorite viz software.

Best,
Ray
