Help! for the love of all that is good.

So after two weeks of struggling with this model, it took this long to figure out that hyperelastic materials are not valid for 3D elements in ABAQUS. I got some default experimental data for the rubber and I used it in this model. All lengths are in mm since abaqus defaults to .04 length when you input .045 for a radius. Therefore all material parameters and loads are in N/mm^2 or MPa. However, in spite of all this, I am still having convergence issues even with a load as small as 500 KPa. The input file is attached. Please, if you look at the input file and run it or anything like that, post something about it, anything. Otherwise, what would be the point to look at it and not posting a thing. Anything would help me right now because i am stumped. Im getting excessive distortion errors so the only thing I can think is that the load is too big which makes no sense or the mesh is not fine enough. Thanks.
