Creating Core Samples

Group List displays all the core sample groups present in the model.

1. Select a core sample group in the list.

   Tips: When you start Multiple Core Samples, a core sample group feature is created as the current group in the list. When you edit an existing core sample group, that group is the current group in the list.

   The dialog box is populated with the information of the core samples of that group.
2. Alternatively, click New in the list to create a new core sample group.
   • The core samples are created as CS.x under a Core Sample Group under Review tools. Both are editable.
   • A standard name is proposed, such as Core Sample Group.x
   • A label with a leader line is attached to the core sample.
     • The label is always parallel to the screen.
     • Whatever the zoom factor, the size of the label remains the same.
     • Drag the label to position it.
       Note: The dragged position is not kept.
     • Change the color of the label and of the leader from the graphic properties.
       Note: You cannot edit the size or the font of the core samples texts.
3. Hide or show individual core sample groups.
4. To customize the name of the core sample groups, key in a Group Prefix and a Group Starting Index. Click Rename Group.
   • The name of the Reference Entity (if any), is proposed as Group Prefix.
   • If the group was created from several reference entities, the name of the last reference entity used is proposed.
   • The core sample group is renamed from the value of Group Prefix.
   • The core samples in the group are renamed from the group name and the index.
   • The tree is updated accordingly.

• Selecting a plies group reverts to selecting its associated surface. All the plies of the plies group found along the normal to its surface are processed.
• If the selected surface is not that associated to the plies group, points selected on this surface are processed as follows:
  • The first plies group found is represented by the yellow lines (plies) and the purple line (its reference surface).
  • The selected surface is shown in red.
  • The blue arrow points to the selected point.
  • The dotted green arrow shows its projection on the reference surface of the first plies group found.
  • The green line is the normal to the reference surface of the plies group at the projection of the selected point.
  • Multiple Core Samples processes all the plies of that plies group found along this line.
  
  
  

1. Select a reference entity

   It can be:

   • A grid or a virtual stacking: A point is created at the center of each cell of the grid.
   • A zones group: A point is created at the center of each zone.
     Note: If the zone contains a transition zone, the point is created on the portion with no transition zone, meaning it is not at the exact center.
   • A plies group: A point is created in each surface with a constant thickness area.
   • An Iso-Thickness Areas group. The ITA points from the group are used as locations of the core samples. This way, you can mark zones with the same thickness if an ITA group already exists.

2. If you have selected a plies group, define the width of the areas to consider. Either key in a value, or measure the distance between two plies.
3. Click OK.

• Index is the order of the core samples.
• Name is the name of the core sample. Click a name to edit it.
• Surface Reference
• Ply is the name of the ply found under the point. It is not editable.
• Thickness is the value of the laminate found under the point. It is not editable.The computation of thickness may be inaccurate when the computed equivalent shell of a core is not the same as the cross section of a core that touches or is nearest to the support surface.
  
  
• Point is the name of the point you have picked. It is not editable.
• Hide/Show indicates the visibility status. Click either Hide or Show to modify this status.
• Direction can be Normal (to the surface) or Invert. Click Invert direction in the dialog box, or the arrow in the work area to modify it.
• Cut-Pieces, Non Struct Plies and Filters are the options selected for the core samples as you picked the point.
• Reference Entity
• Difference

Results is enabled only when you select one core sample.

• List of Plies lists the details of the plies.
  • Number of entities
  • Total thickness
  • Plies groups
  • Sequence
  • Entity
  • Material
  • Thickness
    Notes:

    • For plies and cut-pieces, the corresponding material thickness is shown.
    • For cores, the length of intersection between the solid of core and the core sample line is shown.
  • Direction Name
  • Direction Value
  • Rosette
• Thickness Law lists the details of the thickness law of the core sample:
  • Material
  • Thickness law as a number of plies and percentage for each direction
  • Total number of ply for each direction if there is more than one material
• Delta Comparison lists the delta found when comparing the core sample and the entity thickness law.
  • Name of the entity.
  • Material
  • Delta
  • Details of the directions
  • Status of the delta
  • Status of the thickness
  • Total delta difference
  • Thickness difference between the core sample and the reference entity
