WebbA geometry optimization is the process of changing the system’s geometry (the nuclear coordinates and potentially the lattice vectors) to minimize the total energy of the systems. This is typically a local optimization, i.e. the optimization converges to the next local minimum on the potential energy surface (PES), given the initial system ... WebbIn most cases these criteria need not be adjusted. In nonlinear problems the governing balance equations must be solved iteratively.

Webb4 nov. 2024 · For those using finite element analysis, the term “convergence” is often used. Most linear problems do not need an iterative solution procedure. Mesh convergence is an important issue that needs to be addressed. Additionally, in nonlinear problems, convergence in the iteration procedure also needs to be considered. WebbBut in some cases, it simply can't converge on a best fit, and gives up with the message 'not converged'. This happens in two situations: •The model simply doesn't fit the data very well. Perhaps you picked the wrong model, or applied the wrong constraints. •The initial values generated a curve that didn't come close to the points.
