What's going on here, why is it over precision, and what does BIEF mean, and there's an accompanying picture that also shows super precision.
The situation is as follows:
EQUNOR (BIEF) : EXCEEDING MAXIMUM ITERATIONS:    1000 RELATIVE PRECISION:             NaN
 GRACJG (BIEF) : EXCEEDING MAXIMUM ITERATIONS:      50 RELATIVE PRECISION:             NaN
 GRACJG (BIEF) : EXCEEDING MAXIMUM ITERATIONS:      50 RELATIVE PRECISION:             NaN

Hi
Telemac us iterative solver with a maximum number of iteration to avoid infinite loop.
In your case the solution didn't reach the precision criteria before the max number of iteration. This mean the solution is probably wrong at this moment.
You should investigate the evolution of results during the time-step before

Hope this helps
Christophe
