[gmx-users] shake and settle
Hi gmx user I want to use shake algorithm for bonds within protein and settle algorithm for the bonds of the water. How do I specify two different constraints algorithm in pr.mdp file?

[gmx-users] shake vs settle for water
Hi All, I am using Groamcs 3.2.1 for my simulations, I am having some problems with an interfacial system when I use SETTLE as opposed to SHAKE to constrain OH bonds and HOH angle in water. As a matter of fact I did various simulations of liquid vapor interface simulations of water, SETTLE gives me absurd numbers while SHAKE gives consistently good results . I have looked up the mailing list as well as manual for differences in SHAKE and SETTLE, but apart from the statement that SETTLE Is better than SHAKE I dint find much. Any ideas on how to resolve this. When I look at OH bond and HOH angle distribution from SETTLE and SHAKE its precisely same. Any insights would be helpful, Thanks Rahul ___ gmx-users mailing listgmx-users@gromacs.org http://www.gromacs.org/mailman/listinfo/gmx-users Please don't post (un)subscribe requests to the list.
