Re: [AMBER] Query about switch function using AMBER ff99SB forcefield and NAMD simulation code

the ff99SB force field was not directly developed with a cutoff or switch,
but it's likely that the water model you are using was indeed developed with
such things in mind and you should use the options that are appropriate for
that model or you may get quite incorrect results.
