Step increments. Plasticity algorithm warning

gigicap
Hi all, i modeled a facade of a masonry building as 2d shell of no-tension material. I imposed displacements and i did analisys with mohr coulomb criterion. These warnings occurs: - the plasticity algorithm/ creep / connector friction did not converge at points... - force equilibrium accepted using alternate tolerance - the strain increment is so large that the program will not attempt the plasticity calculation at points... These errors occurs: -time increment required is less than the minimum specified. How can i fix these errors and warnings? Is there a way to see the results of every increment in a step? Thanks for your attention!

I think you can specify the time increment before running the model through: Mesh- Verify mesh-Size metrics-stable time increment-Highlight then you will find the Smallest stable time increment at the message area below
 you just need to input this value
