Is it possible to use beams & solids together in Mechanica Wildfire 2.0?
I have frame rails connected by crossmembers which are structural c-channels, and I'd like to approximate the crossmembers using beams, while keeping the frame rails as solid elements. So I created datum points on the frame rail parts, and used those datum points as the endpoints when creating my beam idealizations. However, the run terminates with a fatal error, saying the model is underconstrained. As soon as I take my beam elements out, the model runs fine. What am I doing wrong, or is this something Mechanica just can't do?
