High friction (typically coeff. of friction higher than 0.2) between surfaces can make the stiffness matrix unsymmetric. Sometimes, such cases may face convergence issues in which case using an unsymmetric Newton-Rapshon solver is helpful. In your case, if you did not run into any convergence issues and have a solution (all green check marks on model tree), then you may ignore this message. If you run into convergence issues, then changing the Newton-Raphson option (Analysis Settings --> Nonlinear Controls --> Newton-Raphson Options) to Unsymmetric could be helpful.n
