That does not look like an MFiX screenshot to me - what software are you using to make this plot?

#3

I am using the ParaView software for makeing the plot.

You most likely have a line resolution larger than the number of MFiX cells, so you get several points within each cell. Each point within a cell will have the same value, hence the staircase look. Use the same line resolution as the number of cells.

Select “Sample at segment centers”, when doing “Plot over line”, which is what I expect you’re doing. You’re getting the steps because you use the default “Sample uniformly.”

This is how it looks on my end when I toggle between the two:
