Add Geosynthetic

The Add Geosynthetic option is used to add planar 2-dimensional Geosynthetic support elements to a model. Geosynthetics are added as quadrilateral planar support elements as described below.

Before you can add GeoSynthetic support, two conditions must be satisfied:
  • You must first define at least one Geosynthetic support type in the Define Support dialog, before you can Add Geosynthetic. If no Geosynthetic support types have been defined then the Add Geosynthetic option will be disabled.
  • Geosynthetic support can only be added to planar surface geometry. Therefore your model must have a planar geometric surface defined for each layer of Geosynthetic support that you wish to add. If these surfaces do not exist, then you will have to add them (e.g. with the Add Plane option) and then you can add the Geosynthetics to the surface(s).

Once the above conditions are met, Geosynthetic support can be added as follows:

  1. Select the Loading & Support loading and support icon workflow tab.
  2. If necessary use the Visibility settings in the sidebar to hide the geometry volume(s) above the surface on which you will be adding the Geosynthetic so that the planar surface can be selected.
  3. Select Faces Selection face selection icon as the Selection Mode.
  4. Select a planar surface on which to add the Geosynthetic support.
  5. Select Add Geosynthetic add geotextile icon from the toolbar or the Support menu.
  6. You will see the Add Geosynthetic dialog. In the dialog:
    • Select the Support Type property you wish to assign to the Geosynthetic.
    • Enter four points defining the corners of the Geosynthetic. You can do this graphically with the mouse by clicking on the selected surface, or entering XYZ coordinates in the edit boxes.
    • A Geosynthetic support element is a general planar quadrilateral defined by four points; it does not have to be a rectangle.
    • Select the Anchored condition for each edge of the Geosynthetic. Typically the slope face edge will be Anchored and the other three edges will be free (Anchored checkbox turned off). The Anchored checkbox determines whether the pullout or stripping failure modes can occur along that edge.
  7. Select the Preview Geosynthetic button to preview the Geosynthetic you have defined. If the location or Anchor conditions are incorrect, edit the coordinates as required.
  8. When the Preview is correct select the Add button to add the Geosynthetic to the model.
  9. Select OK to save the settings and exit the dialog.
  10. To add additional Geosynthetics repeat steps 2 to 9 as necessary.
