Convert F04 to another file type
To convert F04 summary logs to another format, you need MSC Nastran or other Data software.
Convert a file to F04
To convert other file formats to the "FEA Results Log" file type, you need software like MSC Nastran or a similar tool.
About F04 files
A .F04 file is an execution summary file generated by MSC Nastran, a leading Finite Element Analysis (FEA) solver suite. This file logs crucial database allocations, disk space usage, memory management, and CPU processing times during a complex engineering simulation run. Engineers use it primarily to debug failed runs or optimize the performance of massive structural models. The .F04 format is proprietary to the Nastran ecosystem and is highly technical. It does not contain 3D visual geometry, but rather raw computational log data. Sharing this file with project managers or clients who do not possess a costly Nastran license is impractical. Users frequently need to extract the performance metrics or solver errors from these files to present them in standard reports. The best conversion targets are TXT for universal reading without specialized software, CSV to format tabular solver performance data into spreadsheets, or PDF to securely share the execution log. Because this is a highly specialized engineering output file, standard online converters fail to process it. The format relies heavily on legacy Fortran output structures that only the original software can properly format. However, convert.guru can still identify the file format, inspect the file, and show text or internal content. Just drag and drop your file to see what it is and convert it if supported.
Convert.Guru analyzes your F04 file, detects the exact format, and lets you read the text inside.
Users also converted F03, F05 and F99 files.
FAQ
If you want to convert F04 file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use MSC Nastran or similar software from the "FEA Analysis Execution Summary" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to F04, try MSC Nastran or another comparable tool in the "FEA Analysis Execution Summary" category.
The F04 Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our F04 converter.
