Abaqus Standard, solid model, zero VOL. FLUX warning

[mechabaqususer]

Hello,

I have a solid model - a half of cylinder. Inner surface of cylinder is loaded with constant pressure (general static analysis). Material is defined as hyperelastic. When i run the simulation, next warning appears:

There is zero VOL. FLUX everywhere in the model based on the default criterion. please check the value of the average VOL. FLUX during the current iteration to verify that the VOL. FLUX is small enough to be treated as zero. if not, please use the solution controls to reset the criterion for zero VOL. FLUX.

I don't know what's wrong. Can anyone help me?

Is it possible that this warning is connected with fact, that there are regions with different elements used (hex, wedge)? Thank's for answers.
