VUMAT
Thanks alot, you gave a big favor to me and I appreciated that.
So I have to define all tensor component individually as sate variables alike before I did and then I defien the number of state variables in DEPVAR option as well as user material constants. I have done it. Then as you told all the state variables must be shown in field output? you mean when we define state variables and update it then we can observe the SDVs at the visualization modul\odb field output or it will save in a separate file???
