Cylinder - plate contact

I'm trying to evaluate the rolling resistance of a cylindrical wheel of different materials on a flat surface. First I wanted to prepare a simple model of a quarter of a cylinder and half a plate, both from identical material and both as shell elements, to calculate the size of the contact surface. I followed Cyprien's tutorial on sphere-sphere Hertz contact (https://_www.youtube.com/watch?v=KVBhOaLh_Is&t=2350s) and the tutorial on https://_www.code-aster.org/V2/doc/default/en/man_v/v6/v6.04.222.pdf.
I definded the plate and cylinder as shell elements with modelisation DKT and asigned thickness with AFFE_CARA_ELEM and COQUE.

I attached the error message, comm and med files. The problem is that I don't really understand the google translation of the error message and I suspect I am doing something very wrong.

Re: Cylinder - plate contact

Dear SVANTEVID,

You are trying to make a contact with two plates by their thicknesses, not their surfaces.

I guess a better approach would be, in this particular geometry, to use CPLAN or DPLAN models.

Best regards.
