AW: scnb value to prevent VDWs scaling

From: Norman Geist (

scnb = "scale non bonded"


so common sense would say that a factor of 1 will not change anything to the
incoming ff.

Hi all

Didn't get a response to this and I really need an answer so I thought I
should bump it.

Please if anyone has an answer for me it would be much appreciated.

I'm trying to find out what scnb figure in NAMD results in no scaling. I
gather from the user guide that the default is 2 and that the VDWs
interactions are divided by the scnb value.

It seems to me that an scnb value of 1 would then be required to achieve no
scaling (or a scaling factor of 1 anyway) of VDWs interactions. Just thought
I would check. Am I correct in this?
