Dynamic mesh for 2D axisymmetric mesh

  I'm trying to integrate a dynamic mesh, where this box moves inside a 2D axisymmetric domain. I was able to to get this case to work for a non-2D axisymmetric domain (no line of symmetry). I receive a segmentation error saying that I have negative cell volume or an error saying that the fluent process couldn't be started.
  Do you know how I can find the coordinate position of the negative cell volume? The settings I am using are copied below. Thank you!

  Hello Zoelle,
  can you add the axis as a deforming zone in your Dynamic Mesh settings?
  I suspect your negative volume cells will be found on the right of your moving wall. You can do contours of Mesh > Cell Volume and set the max value to 0, or contours of Mesh > Mark Poor Elements.
