Difficulty in analyzing automotive tire in workbench

Click For Summary
The discussion revolves around challenges in analyzing automotive tire behavior under pressure using ANSYS Workbench. The user initially struggled with convergence issues when applying the Mooney-Rivlin material model, which was resolved by reducing the applied pressure significantly. Suggestions included using a non-linear solver, increasing substeps, and gradually applying pressure to improve convergence. The conversation also touched on the complexities of tire modeling, emphasizing the importance of including structural reinforcements for realistic simulations. Ultimately, the user successfully modeled the tire and sought guidance on analyzing its rolling behavior on a surface.

Well it depends on what conditions you want to analyze it under. You need to consider things like angular speed (centripetal acceleration), applied torque, and load it's supporting. You're going to have to decide how you want to approximate ground moving by as well.
