hi, I wanna ask, why is my fea result is different if I define my part as solid or beam. isn't it supposed to be the same? What makes both got different result? Could you someone tell me more about the condition when to use sheet, truss ,beam or solid. In my opinion, I thought that to get accurate result, Solid type must be used as it represent the exact shape of the part. Please need advice on this matter, still confusing me and very hard for me to decide what to choose.
sorry for not posting the example. I was just running the same test as figure shown below.

Throughout the simulation, I have tried change the beam as a solid type and beam type and comparing the results, and as per mention previous post, the result isn't the same. That put me in confusion for the usage of beam and solid type element.
By the way Jared, thanks for the reply and tips given, AFNOR really good resource of references.
i'm not sure i understand the question?
in the real world, everything is a solid
we use idealizations to reduce computation time and they are equivalently accurate if defined equivalently
i would recommend posting some examples and the theory you are comparing them to and any assumptions you feel you are making
look for the AFNOR guide, it has many examples of the different idealizations
