How can I get the moment on solid elements in Finite element modeling?

Unlike shell elements, solid elements have three degrees of freedom. So how can I get the values of moments after I run the model/analysis on ANSYS / ABAQUS ?

Does ANSYS consider the thickness of the shell181 element for the stress results?

Is the stress throughout the thickness of the shell element the same? I learned that transverse shear stresses are accounted for in SHELL181 but I also read that stresses in shells along the...

Why do SOLID185 and LINK180 behave different on ANSYS although they have same DOFs?

Both Link180 and SOLID185 elements have 3 degrees of freedom each (translation along the x, y and z) with no rotation allowed. But why do both behave differently under applied load? Why does...

Why is shell element preferred over solid element in ANSYS APDL for bridge modeling in finite elements?

For modeling bridge deck slab on ANSYS APDL, why is shell element preferred over solid element? I read somewhere that the mesh of shell elements is more efficient than solid elements. Why is that?
