Hello.
I've been trying to simulate wear in ANSYS for about two weeks now, but now I'm facing another error. An error occurs when calculating wear in ANSYS using the Archard model:"The solver engine was unable to converge on a solution for the nonlinear problem as constrained. Please see the Troubleshooting section of the Help System for more information". I'm trying to simulate a standard wear problem: the indenter is pressed into a rotating disk, you need to find out the wear of the indenter. The simulation takes place in module the transient structural. So far, I'm trying to simulate at least 5 seconds of this wear. I set the disk rotation via APDL using the CMROTATE command. The indenter is limited on the X and Z axes, the disk is limited on Y and Z (also tried to limit only on Y). All settings for frictional contact and analysis settings are shown in the screenshot. The second screenshot also shows the zones that are highlighted by Newton-Raphson Residential Force. 3 screenshot shows the grid, it seems to me that it is quite small.
Thank you very much in advance. I've already tried to do more sub-steps, but it doesn't help.
May be you should define Archard Wear law . While defining the the contact you can introduce these commands.
