How to add material properties varying with temperature?

Creator

I have to create a new material with Youngs modulus and other properties varying with temperature. I have material datas at around 100 different temperatures. How I can do that in NX Nastran 7.5?

Material properties are entered on MATi cards - MAT1 for isotropic, MAT2 for anisotropic shells, etc. The values entered on these cards are constant.

 

To specify a temperature variation, include an associated MATTi card with the same MID as the MATi card.

 

So, to specify temperature varying Youngs Modulus for an isotropic material, the deck should contain a MAT1 card and a MATT1 card with the same MID.
