As in the last few days or weeks there were at least two posts where it looks that further Forcite+ runs are needed and to keep the confined layer.

There is an undocumented functionality which retains the confined layer and which can be used via MaterialsScript. It is assumed that the directions C and z match.

Modules->Forcite->ChangeSettings([

UseConfiningField => "Yes",
ConfiningFieldStrength => 10000, # Confining field strength in kcal/mol*A^9
ConfiningFieldShift => 2.0, # Distance from the wall in Angstrom at which the confining field diverges (Angstrom)
ConfiningFieldDirection => "C", # direction along which the field is applied

]);

There is an example attached.

Please keep in mind that scripts come as they are without any warranty and entitlement to get support for them. There is not guarantee that they really do what they claim to do.
