I am looking for a method to fixture a rotating disk which allows the inner bore to expand in a simulation. A centrifugal load is applied to the outer diameter of the disk.
Using the 'On Cylindrical Faces' fixture restrains the model successfully but does not allow the inner bore to expand, which I need.
Using reference geometry between the inner bore and axis restrains the model the same as the 'On Cylindrical Faces' fixture, which does not allow the bore to expand radially or axially either.
These are two methods which restrain the model and allow the simulation to run successfully, but as I said I need the inner bore to be allowed to expand radially and axially.
Any help/advice is welcome, thanks!
