Hi everyone..
using the version 5.2, in the variable expression i try to use sinh(phi) or cosh(phi) and give them a name. the unit of (phi) is the volt wich is the variable of electrostatic module, but the color is orange and show ''unexpected unit of input'' so i can't use it in boundary condition ad i can't solve my problem
Appreciate much for your help!!

Since hyperbolic functions are transcendental, they take unitless quantities as arguments, and thus I'd try dividing phi by some value, like 1[V]
sinh(phi/1[V])
or
sinh(phi/1[µV])
sinh(phi/1[V])
or
sinh(phi/1[µV])
