Hi Gromacians<br><br>I have created two liquid-liquid interfaces by combining
three (DCE-Water-DCE) boxes. I want to calculate the Interfacial surface
tension by using the surface tension option in Gromacs.<br>I know that I
need to give two values for ref_p one for xy and other for z. it was
said in the manual that the "first value should be reference surface
tension times the number of surfaces".what does it mean? what is this reference surface tension and what value i should put to calculate the surface tension? i know that the ref_p
for z should be 1 bar (correct me if i am wrong) Further more how come
ref_p unit will be bar nm for xy and for z it will be bar? any help is
highly appreciated.<br>
<br>Regards<br>Vinoth
