A 1D heat transfer model, cooling from two terminal points, the initial condition is T0, the boundary condition is T0-B*t (B is the cooling rate). I want to know the time needed when the temperature reduced to Tp (just an example) for every point (or mesh node?) in the domain. I know I can make it during postprocessing, but it's not convenient.
My current way is defining a variable, for example, time=(abs(T-Tp)<=e)*t, where e is a small value. the disadvantage of this way is that if e is too small, time will be zero, if e is too large, there will be more than one values for time for certain point.
Do anybody have better ways?
