[gmx-users] about normal pressure and constant area

[Ramon Reigada]

We are trying to simulate a langmuir monolayer and we would like to 
adjust the normal pressure to 1at by scaling the z-axis of the box, and 
keepin the box x-y area constant (surface tension will vary). This is 
done by Lindahl et al in JCP 113, 3882 (2000).

A possibility to do this is to choose 'surface-tension' option in 
pcoupltype and then assign a 0 x,y-compressibility, but we are sure that 
there exists a more elegant and direct way to do so.

   thank you very much to all contibutors in the list
