<P>Dear Gromacs Users,</P>
<P>When I run the tutor/water example, I changed the pressure coupling type to surface-tension and set </P>
<P>compressibility =4.5e-5 4.5e-5 ref_p =1.0 1.0 </P>
<P>I expect the trajectory and velocity should have some changes.</P>
<P>However, I could not find out any change. </P>
<P>Appreciate if you could point out what is the problem?</P>
<P>Thanks!</P>
<P>Albert</P>
