Performing a Numerical Analysis

Numerical Analysis computes the area, mass, center of gravity and mass on a ply, a sequence, a plies group, or a stacking.

  1. Select the element to analyze:
    • A grid
    • A stacking or portion of it
    • A zones group or portion of it.
  2. If required and possible, select the Take cut-pieces into Account check box.
  3. If required, select the Take Core thickness into Account check box.
  4. If required, select the Compute analysis with ply and core shape simulated at thickness check box.

    • Compute analysis with ply and core shape simulated at thickness is more time consuming but also more precise.
    • Compute analysis with ply and core shape simulated at thickness includes Take Core thickness into Account

    1. Optional: Edit the Refinement Factor.

      Refinement Factor improves the accuracy of the tessellation used to compute the numerical analysis, but has an impact on computation time. The lower the value, the greater the accuracy of results, but also the computation time. The minimum value is 0.02. The maximum is 10. The default is 1.

    2. Optional: Select the Display normals check box.

      The normals used for elevating each vertex of the tessellation triangles are displayed. The normals direction and their density help you specify the Refinement Factor.

    3. Press Compute.
    Messages are displayed if there are errors on plies, or if a core does not lie completely on the support surface.
    Notes:
    • Results of this option are not persistent: you have to export them to keep them.
    • If plies are defined on two overlapping support surfaces, the thickness of plies on first surface is not considered for plies lying on the second surface.
      Recommendation: In such a case, define all the plies on a larger single surface.
    • If the top surface computed from Plies Group.1 is used to define plies from Plies Group.2, the thickness of plies added to Plies Group.1 after the computation of the top surface is not taken into consideration for the computation of plies from Plies Group.2.
      Recommendation: In such a case, recompute the top surface after having added plies to Plies Group.1, and define the plies from Plies Group.2 on the new surface.
  5. Click ... to enter a storage directory and file name to export the data. Click Export.
  6. Select a Material to filter the results.

    Filtering through Material is only possible if you have selected at least a stacking as input.

  7. If available, select the Persistent option to featurize and display the analysis in the tree.
