Replace Orientation Nodes By Coordinate

Beam/bar orientation can be defined by specifying a node (internally the solver calculates the vector).

In order to provide the correct offset from underlying shell elements, it is useful to have the beam orientation using the coordinate system (vector). This function does the conversion from node to vector.

  1. From the menu bar, click Aerospace > Beams > Replace Orientation Nodes By Coord.
  2. Select the 1D elements.
  3. Click OK.
    If the orientation nodes are not used they are suppressed. There is a mix of CBAR and CBEAM elements using the same section shape. With CBAR elements, the solver enforce shear center matches with the centroid (neutral axis). With CBEAM elements, there is a distance between the shear center and neutral axis. In order to place all of these beams as stiffeners on top of a shell, an offset is applied to the elements.
