title: Get interation number in UMAT
body: <p>Although it is easy to get the current step or increment number (variables KSTEP and KINC), I can't find an easy way to know the iteration number when inside the subroutine UMAT.</p>
  
  <p>I know the following "if clause" will tell me if I'm in the first iteration of the first increment of the first step:</p>
  
  <p><code>IF((KINC.EQ.1).AND.(SUM(STRAN+DSTRAN).EQ.0.0D0)) THEN</code></p>
  
  <p>And I also know that I can get the iteration number writing to external files. However, is it possible to do it just inside the UMAT subroutine?</p>
