Prediction — Simulation starts before the solver
For the rectangular section:
I = b·h³/12
I = 0.05·0.10³/12 = 4.16667E−6 m⁴The Euler–Bernoulli tip deflection at the end is:
uy_ref = F·L³/(3·E·I)
uy_ref = −3.80952E−4 m = −0.380952 mm
M07 uses KEYOPT(2)=3 and obtains approximately
−3.79470E−4 m at the corner node. Before running
M07, we can already predict an average deflection error on the order of
1 %, less than the limit of 5 %.
