Fix missing IPOBO records in SERAFIN (.slf) mesh files generated by q4ts
Project description
fix-slf-mesh-ot
Fix missing IPOBO (boundary node index) records in SERAFIN (.slf) mesh files generated by q4ts. Patches the binary file in-place by reading boundary node numbers from a .cli file.
Installation
pip install fix-slf-mesh-ot
Usage
fix-slf-mesh-ot mesh.slf boundary.cli
How it works
find_ipobo_offset— Parses the SERAFIN binary format (tries big/little endian) to locate the IPOBO record offset. Walks the header: title → variable count → variable names → params → geometry (NELEM, NPOIN, NDP) → IKLE → IPOBO position.fix_ipobo— Reads the.clifile to build a boundary-node-to-index mapping, then writes the IPOBO array at the found offset via a temp file +os.replace.
The SERAFIN format uses Fortran-style records (4-byte length prefix/suffix around each data block).
