What is the difference between RF‑/FE‑LTB and RF‑/STEEL Warping Torsion? Both calculate with on the 7th degree of freedom.

Answer

That is right, both add-on modules calculate with the 7th degree of freedom, the warping. 

The difference is that RF‑/FE‑LTB automatically detects only those loads that directly act on a set of members. Loads from other structural components, that indirectly act on the designed set of members, must be added manually as secondary loads. RF‑/FE‑LTB then performs a complete recalculation of the structural system.

On the other hand, RF‑/STEEL Warping Torsion analyzes the internal force distributions from the calculation of the main program and then calculates the loads back. These are then applied again and calculated. Thus, you do not need to enter loads, which saves your time.
