      Can you share a picture of the mesh? Looks like there are no elements on the surfaces scoped in your contact definition. This happens if your surface dimension is smaller than the defeature tolerance. Reduce the defeature value to a much smaller value. Also change capture proximity to yes. The surface has a lot of split lines which might create meshing difficulties especially if you are using a student license with node limitations. You can use a virtual topology to merge these small surfaces

      . Also if your model is symmetric make use of symmetry boundary condition (

      ). This will greatly reduce the computational expense.

    thank you for your advice. now its clear. after i learn from videos from you. i found the problem. my element size is not small enough to define the small part on my object. thank you
