[Users] GW150914 - error while running simulation

[Krishiv Bhatia]

Thanks Dr. Schnetter.  I really value your time.

Good to know I am on the right path. I am not running on a cluster. It is
my local mac.

I am also running a simulation for 10 hrs and then will run for more time.
I will update you with the results.
