Hello,
I've been doing thermal analyses of some materials in NASTRAN (PATRAN as a pre-processor), doing really simple linear analyses, but a lot of them for different temperature loads (with the same ref. temperature). I have a table of CTEs values for each temperature step temperature (instantaneous CTE), I have run some tests and it seems that NASTRAN takes the value of CTE for reference temperature, which defeats the purpose of applying the table since I need to change it for each calculation. Is there any way to tell NASTRAN to use the average between Temp ref and Temp load, or even just to use CTE for Temp load?
I Hope, I explained my question properly.
