Hi. How do I get the correct material properties when I update the FEM?
When performing a Nastran Update, it seems to output the material properties at the analysis temperature of the last loadcase in the list.
If I split my job into two decks, one for hot cases & one for cold, the composite flange properties (MAT1 cards) are correct in each deck – hot in hot, cold in cold. However, the composite panel materials are all at the temperature of the last load case in the list. Is there a way to ensure that all materials reflect the appropriate temperature? (Each of my decks contains one thermal and one mechanical load.)
If I can't get the properties to match the load temperatures, I’d like to update the FEM for all properties at one temperature for all cases (inc. panels and flanges), so I can use the one deck. Is this possible?.
Re-setting temperatures in the set-up form before updating doesn't affect flanges (I assume they're calculated during sizing & stored elsewhere). Panels seem to all use the temperature of the last mechanical case.
Any tips on controlling material properties when updating Nastran decks would be extremely welcome.
