Post-stress can be added to bars (1583406788339-301.png Initial internal line load) and structural regions (1583406796123-620.png Initial internal surface load) as load. Constant moment and normal force values in a given direction (e.g. only in one direction) may be defined by points of line and planar structural objects.

The initial internal load commands are useful for defining post-tensioning loads in concrete bars and slabs. Post-stress is also good for steel bars at welded connections. The definition steps are the same as introduced at Line or Surface temperature variation load commands.
