lipid bi-layer and SiO2

From: Raul Araya (

Dear NAMD users:

Im trying to perform som MD simulations involving a fatty acid and a
SiO2 surface. I have placed the lipid bi-layer over the SiO2 surface
with and without water at both ends of the bi-layer and I have done
NVT and NPT simulations and in all cases my simulation fails at the
end of the minimization. The lipid bi-layer seem to come apart. That
is, the upper layer starts to move upwards away from the other layer.
Until now I have not logical explanation for this, can any one help me
