I'm having a heck of a time meshing this fairly simple assembly. It seems like I've tried every mesh fineness and tolerance the program allows and still to success. Every time I try with different settings, a different part fails to mesh. Further, I tried the same cross sectional breakup on a shorter W-section (500mm) and the meshing worked fine, but when I made a longer version of the same W-section (~2500mm) the meshing fails every time.
The file is attached. Failure diagnostics say:
Surface mesh successful.Volume mesh failed.Reducing element size or increasing number of elements per circle may help.
Like I mentioned, I tried increasing meshing fineness to a very high value, and toying with the tolerance but nothing worked. I even tried recreating the model thinking there was some geometry anomaly but that didn't work either. If anyone has any suggestions I would certainly appreciate it.
