Deformation in wrong direction with gravity

      Hi,

      I'm trying to model a wing for a static structural analysis, and I'm getting results that don't make sense, as the wing is deflecting downwards, even though the lift force applied is greater than the weight of the wing and the engines. This only happens when applying gravity, as the weight of the engines is imported as external force data, as is the lift distribution, and both are applied using y coordinates along the wing. What could cause the downward deflection of the wing when gravity is applied? Please ignore the strange mesh here, that's a sepearate issue.

      Ok, I realised that the external data to apply the forces wasn't actually being applied, but I can't figure out why this is happening. For all the models I set up previously using this workflow, there was no problem, but for some reason this won't import and apply load data correctly. Is there any way to show where the load is being applied based on coordinates so that I can diagnose it?
