.. _fem_gen_file: Finite Element Analysis - File Generation ========================================== The best way to create a F3D file is to use the FEA report file from a bridge analysis. Best to use a BDF file for a small bridge so the resulting FEA file is not to cumbersome to edit. Before doing a run, either LFR or LRFR, set the AnalysisControls switch "RptFEA" to "Y" .. image:: ../../image/fem_file_gen_1.png :scale: 50% The analysis will generate a ...._Fea.rpt file. Rename the file to any name you want with the extension of ".f3d" Now go to the next step of editing this file :ref:`fem_f3d_file`
