GRIDDATA suitability for interpolating from one mesh to another
显示 更早的评论
Hello all,
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

griddata (in this case griddata3) is going to be removed in a future release of Matlab. Use TriScatteredInterp instead. I've used both and found that TriScatteredInterp is faster and offers more options.
