Hi all,
</p>
<p>
my question is about the history data storage in FEAP.
</p>
<p>
I am writing element subroutine (elmt01) in FEAP 8.3 for a history dependent problem.
</p>
<p>
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).
</p>
<p>
The problem is :: I am unable to figure out how to assign these variables to the history arrays (at t_n+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 <strong>hr </strong>arrays are pointer arrays, not the data storage arrays and in the same manual after a few pages (page: 28), the program uses these <strong>hr</strong> arrays to store the history data <img src="modules/tinymce/includes/jscripts/tiny_mce/plugins/emotions/images/smiley-frown.gif" border="0" alt="Frown" title="Frown" /> .
</p>
<p>
I will be very very thankful for any advice related to this problem from FEA veterans at this forum.
</p>
