forces or pressures and parabolic or triangular trend

if the deformed does not conform to what you expect with all probability there is a mistake in the model.
you have to check:
- total amount of the applied load and generated moment, from the output of the solutor.
- correctness of elastic materials modules
- verify the congruence of the measuring system used. attention that if models in mm the masses go in tons and accelerations in mm/sec.
- verify that the various components of your model are connected correctly to make this advice as well as a debug in the preprocessor, to also turn a modal analysis, without constraints and loads, but only with the applied masses and ask for at least 10 ways.
the first six are rigid motions and must have frequency of 0, the other four are the ways to vibrate for the free structure, if these modes have low frequency, it means that something is disconnected. However, you have to plot the deformities to see the motions.

I have already verified the modal is should be all correct, as I have verified the congruence of the units of measures and the materials placed . the only problem could be related to the applied load that I think is done correctly also because I have tried different possibilities of load therefore using both the rbe3 and instead loading the model directly on the nodes , or switch from a concentrated load to a distributed but still not found the square of the problem. thanks always for availability.

the solutor fe is not wrong, so if the result is orders of magnitude different from how much you imagine, there is a mistake.
loading a wing with rbe3 is practice.
For the rest, I don't think I can help you without a model and hours of debugging
