Hello,
I want to ask for advice how to change boundary condition in time. E.g. I have exact temperature on boundary for 3600 sec. and after this time, I want to change this boundary to insulation. I've tried using Convective cooling function with very high and low user definied heat transfer coefficient as a function of time.
But now, I want to have one boundary that is insulated and after some amout of time it will become Convective cooling (Internal forced convection), so I can't change the heat transfer coef. I've tried to set velocity of external fluid to zero, but it didn't work quite well (still some heat fluxes through boundary).
I've also tried to make more study steps that will continue one after other, but than it's hard to manage with results. Time series results doesn't make continuous solutions, i cant export animations, etc..
I hope, there's some great solution for this, that i've missed.
Best regards, Jan.
