Deleting a Line Created a cx-solution-plot error
 

I am working with Fluent student edition. I was adding and deleting a line to measure pressure in my simulation. After I got my lines how I wanted them, i started getting errors at the end of my run time.

The errors are: "Error: cx-solution-plot: no zones, surfaces or file data specified."

Then: "Error Object: #f"

"Error: Error Occurred during handling message in Workbench: Generic Command"

Does anyone have an idea what this error is and how to solve it?
