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 ?

What is the different between plane182 and shell181 elements in ANSYS?

What is the difference between plane and shell elements in ANSYS? other than the fact that plane has 3 degrees of freedom and shell has 6 degrees of freedom?

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?

What is the type of connection between elements on ANSYS APDL after I merge their nodes together?

For the bridge shown below, the web is connected to both flanges, and the slab is connected to the parapet by meshing and merging the nodes, but what is the name of this connection? is it...

How can I re mesh lines in ANSYS APDL?

How can I re-mesh lines in ANSYS APDL without having to click all the mesh in my model (attached below)? Is there an option where I could clear only the lines meshing without clearing the mesh of...

What do the different colors of mesh mean in ANSYS APDL?

I am modeling a finite element bridge on ANSYS APDL (attached below), and after meshing I am getting these different colors (purple and blue) for my FEM bridge model. I do not know what they...

How to mesh small area on ANSYS APDL?

I am meshing a small area (shell element) attached below and I keep getting errors (attached below). I have tried smartsize meshing on ANSYS APDL and manual meshing. Yet it is not working out....
