In solidworks visualize can animations be generated with 3D people models?

Animations can be created with any 3D models using SOLIDWORKS Visualize ,

in fact you can do all the animating in SOLIDWORKS with a motion study and import in the animation without the need to manually keyframe anything.

Do you want the people to move ... like walking?

Realistic/convincing animation of biped (or quadruped) requires a complete "character rigging" system...AND soft body deformations.  Neither of which is supported by SOLIDWORKS or Visualize.

So while you could technically achieve an animation of a person walking or running, I'm afraid if you rely on manually key-framing in SW (based on mating conditions of a human model), your results will look quite robotic at the very best...and since there is no actual soft body deformation, there will be no realistic skinning (ie stretching of skin at joints).

Realistic/convincing animation of characters is quite a specialized workflow.
