Hi Hendrawan Ariefudin,
There can be several ways for this error to be addressed.
One of which is mesh refinement.You might also access the element which has failed/distorted and you may want to refine the mesh for the respective face.
Also, try checking the contact status using the contact tool (This helps to detect the flaws in contact before solving the actual analysis) and correct the contact using interference treatments, definitions, detection methods, etc. Contact Tool (ansys.com) Connecting Parts Together - ANSYS Innovation Courses
Updating the 'Auto Time stepping' options in analysis settings might be helpful. If you've been using time step, then try reducing the step size and if you're using substeps, then try increasing the number of substeps. This ensures a gradual loading with small increments over each substep.
