How can I resolve the zero flux problem in ABAQUS?Does it mean that I have to change General Solution controls in step module?

 keep getting the zero flux errors in my model.

“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.”

Does it mean that I have to change General Solution controls in soil step module?

I guess by flux it means pore pressure in my model.
