<p>Can you take a look at the memory the code is using? Is there a
large increase before the code stalls?<br>

min. But when we use it to simulate GW150914 BH merger or
solve tov equation with high precision and long time, it seems
that it will stop at an iteration point without any further
output, even an error. What really confuses us is that for
different tests it stops at different points. Could you please
help us find out what goes wrong with the simulation? I will
attach the log.txt and parameter files to this mail. Thanks
for your time!</div>
