Extracting elemental stiffness matrixes

Good Morning,

I would need to extract the stiffness matrix relative to every element of the FE model. I had a look to documentation U1.03.02 in particular the section "Access method to an unspecified structure of data". But onestly i don't really understand how this works.
I also ad a look to the test case sdll123c but again is really not well explained.
What are the basics to access these objects. Which steps should i follow? How do i access the fortnan routines? How do i know which routine does what?
I assume that the routine where the total stiffness matrix for the structure is assembled also contains the elemental stiffness matrixes that i need. How to get them?


Regards,
Massimo
