Using Time in Field Function

maron · October 4, 2013, 05:57

I am trying to set velocity at an inlet with an user definer field function. I have defined a function sin(5*$Time) and when I run I get the error "Cannot resolve function ${Time}: "Time" not defined." Does anyone know how to do this?

Weird, I don't have any issue using $Time.
You are running unsteady right?

I think it was because my function was set to scalar instead of vector and I had to clean up the physics model. I didn't realize that would throw a problem with the time variable but it works now. Thank you for your reply lava12005!
