alkane-silicon_dioxide simulation

Dear NAMD Users:

Im performing some simulations of an alcane box over a SiO2 waffer much like those reported by the people of NAMD with a water droplet, but Im having problems with the NPT simulation paramenters. Most of the time I got an error like this: PME Stray Carges ..... when I use NPT with the flexible cell off.
I can run NPT simulations if I put the flexible cell on and useConstantArea on but the bottom of the SiO2 waffer appear in the top of the simulation box, and I can tell why is that happening.
Please any help on how to do this kind of box over a big surface NPT simulations??? thanks.
