Failed to compute elastoplastic strain variables

Hello, I need help with the COMSOL software, my problem is the following: I want to model an experiment that consists in loading a non-coherent soil by a prescribed displacement. The soil characteristics are: - Young's modulus: 10 MPa - Poisson's ratio: 0.26 - Internal angle of friction: 39 deg - Cohesion: 0 (for convergence reason, I took c=1Pa) The imposed displacement is 20mm (I used the auxilliary sweep option)
the software displays the message: Failed to find a solution for all parameters, even when using the minimum parameter step. Failed to compute elastoplastic strain variables. Returned solution is not converged.
