Menu: Geometry->Divide

  • Volume Sets: Specify a plane which is used to divide the meshes. Several options can be used to enter this plane. With Two Points (the default), the plane is defined by the corresponding line and the direction orthogonal the screen. With Three Points, the plane is defined by three points. When choosing the points, the nodes of the mesh can also be used. After defining the plane, you should choose which section of the mesh should be saved by selecting the side of the plane to use. Only those elements that lie entirely on this side are selected. Only those volume meshes that are shown are divided.
  • Surface Sets: Specify a plane which is used to divide the sets. Several options can be used to enter this plane. With Two Points (the default), the plane is defined by the corresponding line and the direction orthogonal to the screen. With Three Points, the plane is defined by three points. When choosing the points, the nodes of the mesh can also be used. After defining the plane, you should choose which section of the mesh should be saved by selecting the side of the plane to use. Only those elements that lie entirely on this side are selected. Only those surface meshes that are shown are divided. When doing a division, there are several useful options inside the Contextual mouse menu (right-click in the graphical window):
  • exact: to do an exact division, i.e. elements are cut to create the division;
  • parallel planes: the remaining elements will be the ones between two parallel planes. A distance can also be entered, after choosing this option from the Contextual menu.
  • Lines: (Only for surface sets) Specify a plane which is used to get the lines on one side of this plane. On a surface mesh it will extract the edges between elements to the new set.

Original sets are not deleted.

Note: pressing the Alt key while selectinf the second or third point will tie the dynamic line horizontally, vertically or aT 45º angle.
