hi, i'm a student . I have a problem with my FEM model. I have already checked the properties and materials. I performed a modal analysis where the first frequencies correspond to those of a CANTILEVER BEAM to verify that there are no errors in the model. However as soon as I go to apply the loads I get absurd displacements. I applied two loads concentrated around the end of the blade, one simulating the lift equal to 7780 N (z axis) and one simulating the centrifugal force of 178876 N (along y). As a result I get a displacement z z 8 meters long when the whole model is about 5 meters long. What could be the problem?

thank you

I know you said that you checked the properties and materials, I'm assuming that this means your unit system. That would be the first thing that I would have suggested because you may just have a mismatch in your unit system and may not actually have 8 meters of displacement.

Is the screen clip that you are showing from a dynamic animation or is this the shape of the blade initially?

And just to be clear, you have rigidly constrained the blue end as the cantilever correct?
