I get Error No. 2379 "Invalid material data!" in the RF‑CONCRETE Members add-on module, what can I do?


In Window 1.2 of the add-on module, you can clearly which parameters are not valid as they are highlighted in red. However, important are only the materials that are used by the members / sets of members to be designed.

Another problem is a set of members that includes the members with invalid materials. These are also rigid members and similar member types that do not use any valid material.


Invalid Material data 2397
