- The combination info function was expanded so that the deformations associated with extremal support reactions (or vice versa) can be called up.
- You can create load cases with load groups based on the second-order theory or superposition load cases directly from within the Combination info (shortcut menu).
- The labeling of the section integrals has been completely revised. The font size can be changed.
- A new context function allows to change the orientation of model faces.

#### Loads

- The direction of effect of the local line load on areas can now be defined freely. It is no longer linked to the local element system of the area elements. The corresponding representation has also been improved as a result.
- As regards the structure types 2D Frame and Axisymmetric Shell, the material's specific weight is now also calculated for the dead load load type.
- The new temperature load type has been added for all structure types.
- In the FEM system the dead load load type can optionally be defined for each element. This is helpful, for instance, in conjunction with the construction stages.

Memory optimization and parallel processing result in a significant speed advantage over the standard equation solver, especially for large systems. It is activated using the FEM analysis settings. The new module is licensed together with the iterative equation solver.
- The program capacity has been increased to 1 million nodes and elements. This now allows you to analyse structures with up to 6 million degrees of freedom. Depending on the size of the system of equations it may be necessary to use the 64-bit program version in conjunction with the parallel sparse solver or the iterative equation solver.

At present, the calculation is performed for polygon sections and composite sections within the scope of the FEM’s single design. You can activate the new methods in the Design codes dialog of the Options menu.
