Re: How can I see bending and shear moment using simulation?
These types of criteria can only be really viewed with studies that have beam/truss elements.
If you have a solid, you can view shear stresses and strains but no real moments or torques. For a surface (shell) mesh, you can view the top/bottom of the shell and also the like neutral axis in bending, which you may find useful.
In a study with beam elements, after running the simulation, right-click on the Results folder and Define Beam Diagram that will allow you to plot axial, shear, moments and torques.

Re: How can I see bending and shear moment using simulation?
Hi Kevin,
I have done as you suggested and now I can analyze beams.
I have tried to analize a more complex structure built from two beams connected in the middle, the problem is that after meshing the parts that connects the two beam dissapear and when I try to run the analysis I get an error message: "Please define bonded contact sets between beam and solid/shell"
How do I do it?
I have attacehd the assembly and and analysis
Thanks
Gil,

Re: How can I see bending and shear moment using simulation?
Gil,
You must be trying to run a Mixed Mesh analysis which means that at least one body in your study is either being treated as a Solid or a Shell. You must define contact sets between the Solid/Shell body and the beams that it is connected to. There is an automatic feature in 2010 for defining those contacts which works pretty well but sometimes to get the analysis to run properly you still have to add a set or two. Good Luck.

Re: How can I see bending and shear moment using simulation?
Hi Ryan,
Thanks for your answare.
I have tried to look for such an option in the mesh control properties but I did not find it.
Can you please direct me to the location where I can set it up
Thanks,
Gil,

Re: How can I see bending and shear moment using simulation?
There is a Contact Set button in the Command Manager. Once you are in there you can choose a Bonded Contact Set and like I said you can either manually choose what you want bonded or you can try the automatic feature. Hope this helps.

Re: How can I see bending and shear moment using simulation?
Hi Ryan
I think I did not explain myself as I should have
Please have a look at the attached jpg's
one is pre meshing and the other is after meshing.
The connectors holes which are features of the parts that were transformed into a beams dissapear.
I have also attached the entire assembly in the nodes above.
Thanks

Re: How can I see bending and shear moment using simulation?
I looked at your assembly after my last post. What you are trying here won't work. A beam in Simulation is basically just a line between two points with a node at each end and anywhere else another beam is connected. So, when you mesh the two beams in your model the connectors disappear because that geometry is ignored. If you want to continue trying with beams you are going to have to split those connector pieces from the tube and then try and use the contact sets to get them connected in Simulation. That could be difficult. Or, you could just simplify everything, forget the connectors and try to imitate the expected behavior through restraints. Unfortunately beam analysis is pretty limited when there are solid bodies included.
