SUMMARY
The discussion focuses on the discrepancies between hand calculations and Finite Element Analysis (FEA) results for beam bending. The user calculated a maximum deflection of -2.39mm using analytical methods, while Ansys reported an average deflection of 0.3mm and a maximum deflection of 0.8mm. The user identified an error in their calculations, specifically neglecting a negative sign, which led to conflicting results. The conversation highlights the importance of axis orientation and clarity in calculations for accurate FEA results.
