I want to restart the calculation from a defined sub-step within a do-loop. And I get the following warning:

*** WARNING ***                         CP =     226.328   TIME= 13:25:17  Restart for ENDSTEP is not possible from the specified substep since it   is already the end of the load step.  The ENDSTEP option reverts back     to CONTINUE for the restarted analysis.

The do-loop is to change the material of elements that exceed a certain predefined deformation limit.

From the first solution, I have that for the last four sub-steps (77,78,79,80) I should perform the restart to change the material of the elements. But finally, the restart is not carried out as it should be from the corresponding sub-step, but it generates a new load step

I appreciate any help, thank you
