— ENGINEERING SOFTWARE
Calculation software for industrial design and engineering applications
Professional tools for equipment sizing, technical analysis, documented methods, and practical engineering calculations.
/ TRACEABLE RESULTS
Calculations you can cite in your report
Each RJF application turns engineering inputs into traceable calculation outputs, with documented methods, assumptions, and report-ready results.
Use the results for preliminary design, internal review, vendor comparison, and professional documentation across different engineering workflows.
No black boxes
Method-cited results
Windows-native, available now
All inputs map directly to outputs. You see which values drove each dimension—nothing is hidden inside the calculation.
Outputs reference the design methodology applied, giving you traceable specifications ready for inclusion in engineering documentation.
