Hi,

The error you're encountering (SIGSEGV) typically indicates a segmentation fault, which commonly occurs due to accessing memory that you don't have permission to access.

To debug Print out the values of epsi, alpha, and rho_d before using them in calculations to ensure they are not causing any issues.
