None of these "fixes" will do the trick. As I mentioned, it's a plasticity problem, the initial step is an "elastic trial" that can be (often is) outside of the ellipsoid right off the bat. The complexity of the problem is associated both with the fact that we are trying to satisfy equilibrium...

HI there, Here are more information : I am trying to project a point onto an ellipsoid type of shape. The equation is given by f(x,y,z) = y^2 + z^2 - (1- x^2)^2 . I would like to project any random point (x,y,z) onto this surface, but my only constraint is that I must have the absolute...

Dear all, Consider the system given by : http://www.freeimagehosting.net/image.php?53f7eed9ce.jpg where we are trying to solve for s and gamma using Newton's method. It turns out to be a simple implementation. Now, what if we need to impose an inequality constraint on the solution s : one...
