WebMar 16, 2010 · It is proved that solutions of the quadratically constrained least-squares estimator with a semidefinite constraint matrix are both unbiased and consistent in the sense that the averaged problem and limiting problem produce, respectively, unbiased and true (with probability 1) estimators. In this article, we investigate the consistency of parameter … WebI want to analyze this model that is stressed and deformed. I fixed the lowest of points in the x, y, and z directions, and I pulled top of points upward (y direction). When I run the model in Ansys I got the following error: Check for insufficiently constrained model. I tried to cut the model to make it smaller, and analyzed the model like this.
Is it essential to impose error variance while fitting structural ...
WebDec 2, 2013 · I would suggest selecting that Reference Plane, activating the Move command, checking "Disjoin" on the Options Bar, and then moving it 0' in any direction. This will reset any constraints on this Reference Plane and delete the Dimensional Constraint (s).
