Hello
Without more information about the system and the calculation, I cannot give you a detailed solution.
I assume you are trying to analyse the buckling resistance of a beam. The first warning tells you to check the stability of this beam. The BDK manual explains in chapters “2.1 Model System” and “2.2 Boundary Conditions” that only the selected beam is calculated within a larger system.
So maybe the boundary conditions of this beam are not properly defined. To do this, you must create the correct boundary conditions with the “CVA, CVE, CVL, CVM, CV” commands.
Further help can be found within the following TEDDY examples.
