pressure scaling



 dear ccl'ers,
 
could someone explain to me how the isotropic and nonisotropic pressure scaling in molecular dynamics work?
 
can i make big mistake if i use isotropic scaling (nonisotropic is not yet supported by pmemd) for non-isotropic system (solid-liquid interface)?
 thanks for your help. regards,
 lubos
