Temperature mapping.

Hello.

I'm currently working on a thermo-structural analysis of a telescope. The structural and thermal analysis has been carried out separately with different mesh (structural analysis mesh-330000 elements, thermal-5000 elements). The thermal analysis with a coarse mesh comprising of 5000 elements, is done in NX and the temperature data at a particular time step is extracted in excel format. Now, to perform thermo-structural analysis in Hypermesh, i have to map this temperature data onto the fine mesh (330000 elements one). But i'm struck here. I have no idea how to import the excel data. Another problem is that the mesh is also different. I'm going with the optistruct solver as i have to introduce mechanical loads onto the telescope apart from thermal loads.

How to proceed with this problem? any suggestions are welcome. Thanks.
