Searching the tutorials I couldn't find an example of how to use this type of boundary condition, so I've created a very small and simple tutorial. Basically, the setup requires the definition of 4 parameters:
inlet { type oscillatingFixedValue; amplitude 0.5; frequency 0.2; refValue uniform (1 0 0); }
The above setup enables to specify a boundary condition for an entire patch that varies in time as:
