[gmx-users] SHAKEt

[Sekar Ramachandran]

Hi,
I am using SHAKE to constrain bonds during my
simulations.
If I use constraints=all-atoms, my simulations seem to
be running fine. But, If I use constraints = h-bonds
to constrain only hydrogen atoms attached to heavy
atoms, my simulations seem to crash. 
Does any one know how much of a difference does it
make, if one uses on set over the other? Also, if it
does, what would be the best way to correct the error?
Thanks a lot.
Sincerely
Ram
