Error Ansys nonlinear Analysis

Hi
Dear Engineers

I am modelling a nonlinear buckling for a cylinder in ansys workbench and I activated large deflection. and I faced this error :
"
An internal solution magnitude limit was exceeded. Please check your Environment for inappropriate load values or insufficient supports. Also check that your mesh has more than 1 element in at least 2 directions if solid brick elements are present. Please see the Troubleshooting section of the Help System for more information.
"

does anybody know what is it for?

best regards

You may have to post some pictures of your mesh and setup...

This is the modelling procedure :

and this is the mesh:

My setting is:
Large deformation : on
load sub steps: 1000

As a first comment right away, you would need more mesh elements at cylinder cross section/ diametrically... by sharing setup, I would have expected to have some idea or images of fixtures, loads, etc.
