Convergence Issue- Displacement boundary condition won’t solve

    • khouryj

      I am trying to solve a simple 2D system that utilizes symmetry. It seems to be throwing this error regardless of how I alter the contacts and mesh sizing: "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 have attached the file. The tendon body has viscoelastic material properties. The annoying thing is it will solve if I remove the two Tissue bodies, but with the addition of the D_tissue and P_tissue it will no longer solve. 


      Here are the contacts and the initial information from the contact tools.

      And here is the hourglass effect that is happening

      Using the Academic version of 19.2.

      Any help would be greatly appreciated!
