Analysis phases

The complete analysis proceeds in a number of phases. By default, all phases are performed in sequence. It is possible, however, to skip specific phases that might have been performed in a previous run. Three of the process control parameters, FemFlag, PstFlag, and SpaFlag control the execution of the various phases described below.

  1. The reading phase. During this phase of the analysis, the complete model definition is read from the input file or files. This phase is always performed.
  2. The checking phase. During this phase of the analysis, the model is check for inconsistencies or omissions, and error messages are printed when such problems are encountered. This phase is always performed.
  3. The finite element analysis phase. In this phase, the dynamic response of the system is predicted. If FemFlag = YES, this phase is performed, whereas if FemFlag = NO, it is not performed. This latter option can be used to repeat the post-processing phase of the analysis without having to repeat a lengthy finite element phase.
  4. The pre-processing phase. In this phase, two optional pre-processing tasks are performed.
    • SectionBuilder, a finite element based tool for the sectional analysis of beams of arbitrary configuration made of anisotropic materials will be performed. The results of the analysis are used to characterize the sectional properties of beams within the flexible multibody dynamics simulation.
    • NormalBuilder, a finite element based tool for the through-the-thickness analysis of laminated composite plates and shells will be performed. The results of the analysis are used to characterize the through-the-thickness properties of plates and shells within the flexible multibody dynamics simulation.
  5. The post-processing phase. In this phase, the results of the finite element analysis are post processed. If PstFlag = YES, this phase is performed, whereas if PstFlag = NO, it is not performed. The data required for the visualization of the analysis results is computed in this phase.
  6. The signal processing phase. In this phase, signal processing techniques are applied to specific results of the analysis. If SpaFlag = YES, this phase is performed, whereas if SpaFlag = NO, it is not performed.
