Unable to apply AC potential for my boundary in Electrostatics domain of AC/DC module.

i have tried to input in the format V=vo sin(23.1440*t)

where the module is not able to accept the t variable in the time dependant study.

is there any other way to input this sinusoidal potential?

This is only a warning about units. The sine function wants a dimensionless argument. Add a [1/s] unit to t and it will disappear.

Notice the color being orange, and not red, so a warning and not an error. The 40 is the frequency, so with the unit included, you should be good to go: 1000sin(2pi40[Hz]t)
