FortranCallJulia

Embed the Julia runtime inside a Fortran application: Fortran calls Julia through a C bridge (the fcj_* C ABI), and Julia solvers call back into Fortran – one process, zero-copy arrays, every call exception-checked.

Start with the four introduction pages:

• What is FortranCallJulia? – the 30-second tour
• Why Fortran and Julia? – the motivation and the split of labor
• Architecture – the three worlds, with the interactive diagram
• Validation – the three hard metrics and where they come from
