Nastran Thermal: Getting a temperature profile through a plate
Nastran Thermal: Getting a temperature profile through a plate
(OP)
Hi,
I'm quite new to Nastran Thermal and am having trouble with the modeling of a simple 3D plate.
Basically I need to develop a model that will predict the temperature distribution of an aluminum plate that is heated (by friction) on its top surface.
I've tried adding a thermal load (temperature) to both the top and bottom surface to get a temperature difference but get no heat flow when I run the analysis.
Could anyone point out what I'm doing wrong or suggest another way to model this plate.
Thanks

RE: Nastran Thermal: Getting a temperature profile through a plate
Basically you give the top layer of nodes one temperature and the bottom layer another temperature. Then there should be a distribution through the thickness.
BUT if you have used plate elements the the top/bottom temperatures might just represent a gradient. Not a thermal analysis at all. At least not in the context I'm thinking about.
