Cross-Section Interpolation:

- At the position where a design section intersects a tapering beam, an interpolated cross section will be creatred (when CTRL CINT YES is set) and forces will be accordingly transformed. This applies either to automatically detected cross-sectional variations between beam elements or to explicitly given IDs (through DSLN .. NCS .. NCS2 ..) of two end cross sections.
- Standard example: de_07_varying_crossSections.dat

Volume Elements:

- Integration of gauss or nodal stresses from voleme elements (hexahedra or tetrahedra) intersected at a design section is possible using the selection command DSEL.
- Standard example: de_06_volume_elements.dat

Prestressed Quad-elements:

- For CSM Prestressing and Creep+Shrinkage (PC) load cases, only the concrete part of the internal forces are integreated and effects of tendon hole in the concrete are considered automatically by default. At all remaining load cases prestressing forces are integrated at each section automatically.

- When integration of prestressing forces at all the given load cases is desired, it can be manually activated using the CTRL TEND YES command.
- Standard example from CSM: csm4_quad_singlespan.dat
