      I'm doing a mesh convergence study in a static structural module, with 1 million elements I was not getting any maximum stiffness error. But as soon as I refined the mesh and increased the number of elements to 2.5 million it started showing "The maximum contact stiffness is too big. This may affect the accuracy of the results." Can you please let me know the reason behind it and suggest some measures to be taken to overcome this problem?

      Could you check the contact tool results and compare it with results of previous the mesh setting. If there is nothing strange with the results you may ignore the warning.
      Regards Ishan.
