The purpose of opening this issue on Github is to track cases where Newton-Raphson iterations fail to converge for the purpose of having a set of test cases for assessing efforts to improve the convergence algorithm.
The model log file shows the following error message when the DGD Newton-Raphson iterations do not converge:
***ERROR: No starting points produced a valid solution.
