nWhat is you goal? Is it to make a model that gives the same answer as an equation?nOr is it to make a model that will best predict reality? Because those are two different models.nFor example, people calculate beam deflection using Euler-Bernoulli beam equations. ANSYS beam models don't give the same answer as those equations because the ANSYS BEAM188 elements use the Timoshenko beam theory and include shear which the Euler-Bernoulli beam equation does not.nAnother example is equations that use a small displacement assumption. ANSYS models that have turned on Large Deflection are performing a nonlinear solution so will give a different answer than the equation based on the small displacement assumption.n
