hello. I am an undergraduate student from Nanjing Normal University. My
research topic is related to the merger of binary neutron stars. However, I
have encountered some difficulties in generating initial data with LORENE, and
I hope to receive your assistance. Thank you very much.<o:p></o:p></span></p>

Here are my
specific operations: First, I replaced the file "binaire_orbite.C" in
the Codes folder with the one I downloaded in the LORENE folder, and replaced
the file "coal_seq_massscan.C" with the "coal.c" file in
the "/Lorene/Codes/Bin_star" directory of the LORENE folder. Next, I
selected the example in the "Data/AP4/AP4_1.8_1.4" folder on the
website for simulation calculations. Among them, I copied the six files,
"par_eos1.d", "par_eos2.d", "par_grid1.d",
"par_grid2.d", "par_init.d", and
"parcoal_seq.d.40km", to the "/Lorene/Codes/Bin_star"
directory of the LORENE folder. Subsequently, I ran the command in the terminal
of that directory. The specific command I executed is as follows:<o:p></o:p></span></span></p><p class="MsoNormal"><span lang="EN-US" style="font-family: "Times New Roman";">make init_bin<o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-US" style="font-family: "Times New Roman";">make coal<o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-US" style="font-family: "Times New Roman";">make lit_bin<o:p></o:p></span></p><p class="MsoNormal"><span lang="EN-US" style="font-family: "Times New Roman";">./init_bin<o:p></o:p></span></p><p class="MsoNormal" align="left" style="background: rgb(253, 253, 254);"><span lang="EN-US" style="font-size: 11.5pt; color: rgb(5, 7, 59); font-family: "Times New Roman";">
