Hi all,
my question is about the history data storage in FEAP.
I am writing element subroutine (elmt01) in FEAP 8.3 for a history dependent problem (crystal plasticity).
I have written the stiffness
matrix subroutine (stiff01), but it needs the data from the previous
solution steps (previous strains, stresses, plastic strains, dislocation
densities .... nh1,nh2=30 per point).
The problem is :: I am unable to
figure out how to assign these variables to the history arrays (at
tn+1) so that I can get these values back at the start of next step.
In the programmer's manual (page: 8 ) it is written that hr arrays
are pointer arrays, not the data storage arrays and in the same manual
after a few pages (page: 28 ), the program uses these hr arrays to store the history data .
I will be very very thankful for any advice related to this problem from FEA veterans at this forum.
Best regards,
Mubeen
