Dear all,

my name is Lorenzo Cipriani, PhD student at the University of L'Aquila.

My goal is to simulate a BNS merger using initial data computed from Lorene and evolved according to the parameter file I have attached.

Cactus reads the initial data correctly, as you can see in the image "rhoxy_initial.png" but, immediately after, the stars practically disappear from the grid, perfectly cut away (see image "rhoxy_it4.png").

Does anybody have a hint on what might be happening? I have never encountered a behavior like this.

Thank you for your assistance,

best regards,

Lorenzo
