What are the limitations of current bridge researches that involves Finite Element methods and those that don't?


What are the solutions to these limitations?





Please answer clearly and provide links if needed!





Would it be better if we use like other methods like meshless, boundary element, finite volume or finite voulme method to model bridges?

you sound like you know a lot about this, so I am going to offer the information that I know.





Basicly finite element methods are perfect. They are able to give us models that are arbitraraly perfect. I have diped a little in to advanced programs that do the meshing and that stuff, and there is a lot of information about them. Try checking out PATRAN if you want a good start. (just google the name)





The limitations that arrise come from the computer that you are using. Finite element solvers have to be slow because they just have to proform trillions of calulations, thus to get large models you have to have a super computer. It is not that the computaions are difficult it is just that there are so many computations that must be made.





Finite element caculations have the ability to reach the atom (basicly) if you made your mesh small enouph you would be putting in every atom in to your system. This means that the solution would be perfect (with in an order of hbar over two)





Sorry it is not much of an answer to all of your queries, but that Is about all I know about that.
