Hi everyone,

i have a abaqus model where in step one a interference fit is solved and in step 2 i want to add a displacement to the model.

For some reason I end with the Warnings:

The system matrix has 2 negative EV

Displacement increment for contact is too big

Excessive distortion at a total of 23814 integration points in solid (continuum) element.

Any ideas how to solve the problem? (I added my model so you can have a look).

Thanks in advance,

Ciara
