Within this chapter, users will find a general overview of Abaqus solver options, convergence issues, features definitions and usage plus a description of physics the solver can handle. It starts with the vocabulary and translation of error and warning messages in engineering terms; to fix troubleshooting errors, first users need to understand them. Classic preliminary control milestones with tips and tricks are also given to make debugging more efficient. Differences between both Abaqus solvers standard and explicit have been explained with the procedures and option settings, to stop struggling with time increment. Additional solver options and coupled field analyses including CFD are also clearly detailed to get stability and convergence in FEA model. After reading this chapter, users will have gained complementary knowledge regarding troubleshooting prevention.
