Brazillian Disk in Abaqus

[TheodoorVA]

Hi,
i am trying to simulate a Brazillian Disk test in Abaqus but after i apply the force or the displacement i either get errors or the plate (which is suppost to press on the disk) moves through the disk.
does anyone know what i do wrong?

i have attached my Abaqus files below:

this is a print screen from the displacement results:

The orientation of the contact surfaces of the two rigids points in the wrong direction.
I can't use the cae-file from the student edition, so I've switches SPOS and SNEG in the input file and then the contacts work. But then you will see other issues come up during the analysis.
