Hi everyone,
I'm totally new to Autodesk Simulation 2013, but I've been driving Inventor for a good while.
Can anyone point me to a "click by click" idiot guide instruction of how to apply an offset to a rectangular hollow section that is attached side on to a 3mm sheet section? I have tried solidly for 2 days and am totally baffled so I must be missing a fundamental point. What mesh type should it be? I.e.. shell/plate - midplane etc? For hours it kept reverting to "brick" after I repeatedly change it to "beam". So a brief run down of how to setup a basic RHS type beam would also be helpful because I'm really not sure what iI changed to maintain its "beam" type.
I have defined the RHS cross section, which seems correct.
Sorry to be ignorant but I got to start somewhere.
Pete.
Hi Pete,
This is just a guess based on your description, but I think you are confusing the name of the element type with the terminology of your structure. I agree that the RHS (something hollow section?) is referred to as a beam in common engineering language, but that does not imply that the simulation must use beam elements as the element type.
It sounds like you have created a solid model of the sheet and the RHS (stiffener beam), imported that into Simulation, and created a solid mesh. In other words, the CAD model includes the volume of all of the parts, and the simulation model also includes the volume of the parts. The only element type that corresponds to a volume mesh is a brick element (and its cousin, the tetrahedeon). You do not need to set that part to beam elements. You do not need to enter any "offset" because the model includes it already.
Just to elaborate a bit more without going into too much details, here are the different meshes and element types that could be used to represent a physical beam:
If you have more questions, please attach an image of the model or mesh from Simulation.
