Chapter 5: Solution In the solution phase of an analysis, the computer takes over and solves the simultaneous set of equations that the finite element method generates. The results of the solution are: • Nodal degree of freedom values, which form the primary solution • Derived values, which form the element solution. The element solution is usually calculated at the elements' integration points. The ANSYS program writes the results to the database as well as to the results file (.RST, .RTH, .RMG, or .RFL files). The following solution topics are available: 5.1. Selecting a Solver 5.2.Types of Solvers 5.3. Solver Memory and Performance 5.4. Using Special Solution Controls for Certain Types of Structural Analyses 5.5. Using the PGR File to Store Data for Postprocessing 5.6. Obtaining the Solution 5.7. Solving Multiple Load Steps 5.8.Terminating a Running Job 5.9. Restarting an Analysis 5.10. Exercising Partial Solution Steps 5.11. Singularities 5.12. Stopping Solution After Matrix Assembly 5.1. Selecting a Solver Several methods of solving the system of simultaneous equations are available in the ANSYS program: sparse direct solution, Preconditioned Conjugate Gradient (PCG) solution, Jacobi Conjugate Gradient (JCG) solution, Incomplete Cholesky Conjugate Gradient (ICCG) solution, Quasi-Minimal Residual (QMR) solution, and an automatic iterative solver option (ITER). In addition, the Algebraic Multigrid (AMG) solver as well as distributed versions of the PCG, JCG, and Sparse solvers are available for use in Distributed ANSYS (refer to the Distributed ANSYS Guide). See the EQSLV command description for details on each solver, defaults, etc. You can select a solver using one of the following: Command(s): EQSLV GUI: Main Menu> Preprocessor> Loads> Analysis Type> Analysis Options Main Menu> Solution> Load Step Options> Sol'n Control ( : Sol'n Options Tab) Main Menu> Solution> Analysis Options Main Menu> Solution> Unabridged Menu> Analysis Options Release 13.0 - © SAS IP, Inc.
