I am simulating the deflectiopn of a beam with fixed supports at each end with a concentrated load at the middle.  The beam dimensions are 200mm long, 10mm wide, 10mm high.  The load is 100N.  E=2.1e11 N/m^2.  The Simulation result with default mesh is .003429mm.  The theoretical deflection is .00296mm.  +15.8% error.  The deflection equation for a centrally loaded beam fixed at both ends is dy=(P*L^3)/(192*E*I).
