Hi.
'intnormr' is defined in 'Filling of a Capillary Channel—Phase Field' example. Look for it in documentation.
It looks like that:
Name Expression Unit Description
intnormr d(phipf,r)/sqrt(d(phipf,r)^2+d(phipf,z)^2+eps) Interface normal, r component
theta (acos(intnormr))[1/deg] rad Contact angle
