Error: "incremental rotations too large" during non-linear analysis

Hi, I am currently running an analysis of a pressure vessel made from an elastomer material. I have successfully run a static analysis using identical load and boundary conditions. Material properties are from experimental data inputted as simple tension and the Use curve data to compute material constants option. The static analysis completes with no errors and the displacements look as expected. When I run the non-linear analysis I get the error "Incremental rotations too large". Does anyone have any experience of this error and the resolution? I would like to understand what is causing it so I can adjust my setup accordingly. 

 

Thankyou in advance 

 

Mike
