Hi Erik,
I can see from the image that it's possible to apply a temporal variation on the bulk temperature by defining an equation or table, but I'm more interested in having the convection coefficient change value as a function of time.
For example, can the convection coeff in your model (.1 mW/(mm^2 C) change to another value over time? Or is there something in the pull down menu from the pic you've attached that shows this and I'm somehow missing it? thanks!
