Is it possible to have a model of a pipe in Pro/Mechanica an apply a heat rate to it so that it heats up at 20C/hr. This is to find how much the temperature of the outside f the pipe lags the inside temp at certain heat rates.
If you set up a transient thermal analysis, it is not possible to vary a a prescribed temperature, but you can vary heat load or convection condition against time, so it might be possible to do your analysis.
