The profile syntax is in the documentation, I always look it up as I can never remember the header format. Expressions and UDFs are alternative ways to set a changing boundary. Be careful with the initial conditions as they will effect the results: it takes time to move the flow from the initial state to whatever is calculated. nTransient calculations do take time. In CFD you need to resolve the flow timescale (often milli or micro seconds) but run for seconds or minutes. Aim for 10-15 iterations per time step, use parallel and/or a faster cpu and wait. n
