hello everyone

I'm working on SPD process and I have a new method based on compression and expansion in extrusion which results in decreasing grain size .

I want to use Deform 3D and Avrami DRX model (AKA JMAK) to simulate grain size change  because of  the deformation.

1. How do you find the Avrami constants of materials ? Since it isn't available on Deform material library.

2.when I active the Avrami model and grain , at the  end of the process I can't see any grain size calculation while I enter all of the parameters correctly . Where am I wrong ?

3. Please explain me the whole modeling method to calculating grain size in Deform 3D briefly
