The question I have... I would like to use beam elements so the tubular frame chassis will be more representative of welded tubes. I have used other FEA programs in the past that will allow me to "release" a rotation DOF of a beam end to model a pinned condition. Is this possible with Z88? Either in the GUI or even by adjusting some file parameter?
If not, is there some way of mixing beam elements (for the chassis) and using trusses for the A-Arms that are inherently pinned.
Thanks for your help.
releasing DOFs of beams is not possible. The only way is to use beams combined with trusses. But the use of different element types is not supported by the GUI. Theoretically, you can create a model of different element types manually by creating the input files (z88i1.txt, z88i2.txt, ...) with an editor. An idea is to create a beam model first by using the GUI and then run a calculation without clicking "Close" after the calculation ("Z88 ran successfully"). Then you have the solver input files (z88i1.txt, ...) in the project directory. Copy them and converte the interesting elements to trusses manually. You have to correct the number of DOFs! Finally you can calculate the model by the solver. Theoretically, this way is possible, but we have no experience with it. All over that, it is not possible to calculate beam elements while capturing geometrical nonlinearities.
If you have more questions, do not hesitate to ask!
However, thank you for responding... because I will want to mix elements in the future and you have given me a great "How To" with your reply.
