When trying to calculate the design in RF-STEEL Surfaces, I receive Warning No. 1162 - Surface No. XX is of the type "Orthotropic" and cannot be designed. What does this Warning mean?


Orthotropic surfaces are non-linear and cannot be designed within the RF-STEEL Surfaces add-on module. It is still possible to get the full stress analysis in RFEM which can be compared to the limiting stresses manually. Otherwise, the surface will need to be set to "standard" for it to be designable within the add-on module.
