Hybrid analysis: Making the most of FEA by leveraging traditional analysis
CW guest columinst Collin Petersen (Janicki Industries, Sedro-Woolley, WA, US) suggests the use of more traditional analysis methods, where it is sensible to do so, making your finite element analysis (FEA) significantly simpler in the process.
