How do you add multiple point loads in a beam element study?

I'm wondering how to add multiple point loads in a beam element study without receiving the "too short" length:cross-section ratio error.

I have an arrangement as seen in the figure below.


Is it possible?


Also, is it possible to replicate a beam theory study in 3D (Solid Elements)?

If so what parameters need to be applied? i.e How would you simulate a statically indeterminate beam/shaft with multiple lateral loads using solid elements?

The shaft has multiple sections with different diameters thus the need for short spans which produce the error. The reason for split sections is because I have 7 reactions and 6 forces. i.e I require nodes at those locations in the middle of the spans.
