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

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

That is right, both add-on modules calculate with the 7th degree of freedom: warping.The difference is that RF‑/FE‑LTB automatically detects only those loads that act directly on a set of members. The loads from other structural components that act indirectly 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.Meanwhile, RF‑/STEEL Warping Torsion analyzes the internal force distributions from the calculation of the main program, then calculates the loads back. These are then applied again and calculated. Thus, you do not need to enter loads, which saves you time.
