FortranCallJulia embeds the Julia runtime inside a Fortran application: Fortran calls Julia through a C bridge, and Julia solvers call back into Fortran -- one process, zero-copy arrays, every call exception-checked.
The documentation site ships in two languages and is published from this repository:
The same pages build locally with MkDocs, and the bilingual sources live
under docs/en/ and docs/zh/:
pip install -r requirements-docs.txt && mkdocs serveThe generic call path is exception-checked and GC-safe at ~815 ns per call; the Fast Path resolves raw C function pointers for tight loops at ~3.8 ns per call. SciML workloads drop from 17.3 s of JIT warm-up to 1.90 s with the sysimage and a ~12 μs first call under AOT. The four bridge-vs-native acceptance gates report 0 deviations with residuals < 1e-12; the CJ detonation speed is 7.12391 against the analytic 7.12470 (0.011%); and a GRI-Mech 3.0 mixture (53 species / 325 reactions) reproduces the ignition delay t_ign = 1.1075 ms through the bridge.
