Dymore user's manual

This user's manual describes the input that is required to define a flexible multibody system and analyse its dynamic response using Dymore, a finite element based multibody dynamics code for the comprehensive modeling of flexible multibody systems. The input file is divided into the six segments listed below, each segment is introduced by a specific keyword. The six keywords must appear in the input file, file.dym. The various segments control the phases of the analysis.

  1. This segment lists the parameters that control the overall process.
  2. @PROCESS_CONTROL_DEFINITION {
    process control parameters
    }
  3. This segment defines all the objects that define the flexible multibody dynamics model. The objects listed under the Dymore manual navigation panel on the left can all appear in this segment.
  4. @MODEL_DEFINITION {
    ...
    }
  5. This segment lists the parameters used to create finite element model.
  6. @CREATE_FINITE_ELEMENT_MODEL {
    create finite element model
    }
  7. This segment lists the parameters used to drive the finite analysis. The keywords within this segment can appear in any order. If no parameters need to be defined, the corresponding keyword can be omitted.
  8. @FINITE_ELEMENT_ANALYSIS {
    @FEM_CONTROL_PARAMETERS {
    FEM control parameters
    }
    @STEP_CONTROL_PARAMETERS {
    Step control parameters
    }
    @INITIAL_CONDITION_DEFINITION {
    Initial conditions
    }
    @HDD_CONTROL_PARAMETERS {
    Hierarchical domain decomposition
    }
    }
  9. This segment lists the parameters used to drive pre-processing analysis. Both SectionBuilder and NormalBuilder can be run as pre-processors to Dymore. The keywords within this segment can appear in any order. If no parameters need to be defined, the corresponding keyword can be omitted.
  10. @PRE_PROCESSING_ANALYSIS {
    @INCLUDE_COMMAND {
    Include SectionBuilder input file
    Include NormalBuilder input file
    }
    }
  11. This segment lists the parameters used to drive post-processing analysis. The keywords within this segment can appear in any order. If no parameters need to be defined, the corresponding keyword can be omitted. This phase processes sensors, signals, maps, or cross-plots.
  12. @POST_PROCESSING_ANALYSIS {
    @GRAPHICS_CONTROL_PARAMETERS {
    Graphics control parameters
    }
    @PLOTTING_CONTROL_PARAMETERS {
    Plotting control parameters
    }
    @VIEW_PARAMETERS_DEFINITION {
    View parameters
    }
    }
