Re: [gmx-users] clarification of equation 4.65

Seems plausible, but someone would have to double-check the trig. Or
make a test case where theta is 0, and then see whether C4 changes the
potential in a rerun (should be minus) or not (not). Code's in
src/kernel/convparm.c.

[gmx-users] clarification of equation 4.65

2013-06-27 Thread Christopher Neale
Dear Users:

can anybody confirm that there is a mistake in equation 4.65 on page 82 of the 
manual for version 4.6.1?

Specifically, I think that the final term should be C4*(1-cos(4*theta)) and not 
C4*(1+cos(4*theta)) where the difference is the sign of the cosine term ?

Thank you,
Chris.
