Note:  Uniform shell thickness can also be applied under Properties > Define 2D Element properties, but that definition is stored in an attribute file and not in the mesh. Thickness applied here becomes the default when setting up properties for 2D elements. Variable thickness should always be applied here before defining 2D element properties.


Method
  • Calculate

    Mesh thickness will be assigned automatically to each node of the surface element from the thickness information stored on the surface geometry at that location. This thickness can come automatically from the midsurfacing process (including varying thickness) or be applied manually with Repair Geometry > Adjust varying thickness.

    The thickness is defined normal to the surface in both directions. The thickness can be viewed from the display tree by right-clicking Mesh > Shells > Shell Thickness.

    Calculate from solid

    allows you to extract the thickness information of shell elements from the solid geometry around the shells. This is used when the midsurface thickness information is not present on the surfaces. To use this, load the original solid geometry. The shells mesh should be within this geometry. Select the part of the solid to calculate the thickness. This method uses the nearest point projection for thickness calculation. The average of the thickness in both directions is used for each node.

    Piercing

    is an alternative method for calculating the thickness from a solid. It may be preferable for surfaces with greater thickness where the nearest point method may not be appropriate.


    Note:  The nearest point projection and piercing methods lead to similar results for surfaces with small thickness.


  • Remove

    Removes the mesh thickness assigned to the nodes of the surface elements.

  • Modify selected nodes

    Individual nodes of surface element can be assigned a specified thickness.
