Question:
In the case of "free loads", the sum of the loads does not match the sum of the support reactions. Is this a program error?
Answer:
When creating free loads, they are not linked to any object. Basically, "ALL" affected surfaces are loaded. This is also displayed in the attached graphic. If you define a free load (for example, a free individual load with 10 kN) and do not specify any surface, all surfaces affected by this load in the load direction are loaded. If there are two surfaces included, the sum of the support reaction is 20 kN (no further loads are required in the structure).
