Thank you for linking me to this discussion. Unfortunately, this didn't resolve the issue. These spikes I'm experiencing are sort of anomalous since, given the symmetry of the geometry, there should be no reason for these spikes. I was wondering if there is any way to "clean up" or completely remove this outlier from the data, not just mask it by modifying plot attributes. Could it perhaps be a more fundamental issue with the mesh, or could my computer not be up to the proper specs?
