Hello.

I am getting this error when working on a 2D axisymmetric geometry. I have an identical case with a different U and that seems to be running properly. The solver I am using a modified interFoam incorporated with Gauss's Law and charge conservation.

I have included the error message below and remaining stdout and file cases on google drive due to space limitation.

 You must now run the following command to complete the setup:
