Analysis Convergence Guidelines

  • Raphael Jean Boulbes


The introduction chapter has provided a main focus on the methodology to minimize the risk of troubleshooting during analysis. A quality mindset and philosophy have been also given as a recommended way of working and as a good practice to follow in order to conduct an analysis properly. In order to minimize the convergence issue that will be described inside this chapter, there are two important phases to keep in mind to perform analysis as milestones of the modeling process: first, the phase (2) shown in Fig.  1.1 and called the specification of work to define precisely what is the main analysis concern, and second, the phase (5) shown in Fig.  1.1, which is related to the inspections of input data gathered to start computing the model. This chapter now will explain some potential causes of troubleshooting in general. Some convergence issues in the model and some tools will be given to avoid or to fix some common problems during the solution processing.
