I'm working on rolling motion of wheel. 

While solving the model, I'm facing error "The solver engine was unable to converge on a solution for the nonlinear problem". 

Kindly guide me.

Hi Poorva,

It looks like you are facing a convergence issue. Can you plot residuals, and check elements that are distorting?

Also, share the images of contact settings and joint definitions that you have created. It will help us to understand the model and help you more effectively.

Thanks,

Thank you sir for replying,

Sir I'm unable to plot residuals in force convergence. Following are the screenshots for contact settings:

1. Frictional contact:
2. Revolute Joint:

Thank you.

Expand the Solution Information Folder to look for N-R Force Residual plots.

Still It is not visible.

Also I want to create an environment of sand, snow and rocky region for tire grip testing. so please guide me how to proceed.

Please show what items are in the Solution Information folder.  I see a + sign which shows that there are items in the folder to look at.
