Dear Chia-Hui,
Thanks so much for sending the error message. Based on the file you sent, I
was able to push a few bugfixes to the WVUThorns_Diagnostics arrangement.
I also updated the example parameter files and moved them to a new location:
wvuthorns_diagnostics/NSNS_parameter_files
You'll find that nsns_test.par has been updated as well.
Please grab the latest wvuthorns_diagnostics git repo. I'd suggest
comparing the updated nsns_test.par to the version you sent me and
modifying as needed so that your neutron stars are properly centered
(you'll need to replace +/- "20.319527" with the locations of the neutron
stars in your initial data).
Thanks again, and let me know if you run into further troubles.
-Zach
