Where can I find the RF‑CONCRETE NL add-on module? How can I activate it?


The RF‑CONCRETE NL add-on module is a module extension of RF‑CONCRETE Surfaces.

The calculation of deformations in cracked sections (state II) with RF‑CONCRETE NL can be activated by setting the "Nonlinear" method of check in the "Serviceability Limit State" tab of RF‑CONCRETE Surfaces.
