I have a model to apply a RIKS analysis , when I put a load on the structure to buckle it performs well , but when I change the direction of the concentrated force , for example to make the structure to bend , it give this error :
A zero displacement solution was found in the first iteration of a riks step. The analysis cannot proceed. The most likely cause is that all displacement degrees-of-freedom are constrained to be zero.
