VUMAT user subroutine dealing with several integration points

Hello All,

 

I have some questions concerning the VUMAT subroutine, I run successfully an
analysis on one element with one integration point,
so my first question is how to code for several integration points (
nblock concerns only the material points not the integration points)?

My second question is how to write for datas dependent of temperature (like Young and shear modulus)??

Thank you all for your answers.
