Comments

  1. The 2D solid triangle groups cannot contain quad elements (use /GRQUAD instead).
  2. If type is BOX, all elements having all nodes inside the box or on its surface are selected.

    If type is BOX2, all elements with at least one node inside the box or on its external surface are selected.
