Hi,

Is there a way to make the ambient temperature of a fluid(air) depend on time? I have used a function using an expression. While the expression plots correctly, it does not work as an initial condition. (Only takes t=0 as the initial condition) Is there a way to incorporate the changing ambient temperature to the model? (I am modelling the temperature and humidity around greenery throughout the day)

Thanks in advance.

I found this post,

which is the question I am having too. But did not understand the answer correctly.

If anyone can help, huge help :)
