Jacobi

Jacobi is a purpose-built IDE for Abaqus subroutine development: you write your Fortran (UMAT/UEL-style) subroutines, run them against known analytical solutions to verify correctness, and get an AI diagnosis when results diverge, tightening the slow write-compile-debug loop these simulations normally involve.

It targets computational and mechanical engineers who write Abaqus user subroutines and want faster, more confident iteration than a generic editor allows.
