Say we have a laterally insulated beam and some boundary conditions at either end, be it convective or fixed-temperature, but the cross-sectional area is variable. If the cross-section were constant I'd just say it were a 1-D problem, but I'd imagine that having the cross-sectional area be a function of the lateral distance would change this. Conceptually, how would you model it using the heat equation and boundary conditions?(adsbygoogle = window.adsbygoogle || []).push({});

Or does anyone know of literature to explain this?
