Model won't reach equilibrium along interfaces and top

My current model is in MC with standard properties, and I’ve been unable to get the model to solve. I’m currently just using ‘model solve’, but I’m not sure if this is an issue with the model setup, properties, or if I should just be looking to lower the threshold for solving? This is just during the initial setup of the model, after setting all the initial parameters/constitutive models.

There are only two materials at the moment, as you can see in the final picture, and the convergence is having issues along the face between the materials, and along the top of the model.

Where should I be looking for to fix this?

Have you tried ‘model solve elastic’? If the model is still not reaching equilibrium, you can send your datafiles to FLAC2D support.
