[Users] Question about how to generate initial data with an arbitrary EOS

[MAKINO Taiki]

Dear, Beyhan Karakaş

Thanks to your advice, I have successfully installed LORENE and compiled it.

Thank you very much for your assistance.

Best regards,

Hello Taiki,

Here are the resources to create BNS initial data.

Einstein Toolkit supports initial data generated with Lorene, SGRID and Fuka.
Here is the Joshua Faber’s files for BNS ID: https://ccrgpages.rit.edu/~jfaber/BNSID
Here are the recordings on BNS initial data with Lorene:

  *   https://www.youtube.com/watch?v=Lq50IlXBJf8
  *   https://www.youtube.com/watch?v=-NUD-piBeek

Here is the Fuka tutorial for generating BNS initial data: https://samueltootle.github.io/fuka/bnsxcts.html

Best regards,

Beyhan.

Dear Einstein Toolkit Users,

I am a new Einstein Toolkit user, and I would like to ask how to generate initial data with an arbitrary neutron star EOS.

My purpose is to perform binary neutron star simulations with a tabulated or an analytical EOS(for example, a BSk EOS or another tabulated EOS that I prepare myself).

Could you tell me the recommended way to generate such initial data for use with Einstein Toolkit? If there is a related document or examples, I would appreciate it if you could tell me.

Thank you very much for your time and help.

Best regards,
