I would like to use MATLAB for the purpose of transforming a temperature distribution from one finite-element mesh to another. This is to allow the results of a a heat analysis to be used as the load for a thermal expansion stress analysis- the difficulty is that the mesh requirements for the heat and stress analysis are different and exclusive; so the meshes used for the heat analysis and stress analysis need to be different.
The requirement is to take a set of nodes in 3D space, each with temperature values assigned to them, and using interpolation transform the temperature distribution on to a second set of nodes (these will correspond to the same geometry but will be distributed differently). I have looked at the function GRIDDATA which looks to me as if it is suitable for this purpose. Can anyone comment on this?
Many thanks in advance
