Cells and Particles Visualization Issue

MFiX Bug report
#1

Hello,

I have checked the “pseudo_2d_hopper” case and I building a similar model but with different shape, so I imported an stl geometry to mfix. The problem is that the visualization of the cells looks faulty. See the attached photo. Also the “points” pane is disabled, however I allow saving particle data in the “vtk” sub-pane in the “output” pane.

I have checked related topics, however I didn’t find an answer to my issue yet. Please help.
Thanks in advance,
Mariam

Here is the problem. It is blocking most of the cells. Why is this happening?

MESH STATISTICS:
NUMBER OF CELLS = 6900
NUMBER OF STANDARD CELLS = 160 ( 2.32 % of Total)
NUMBER OF CUT CELLS = 66 ( 0.96 % of Total)
NUMBER OF FLUID CELLS = 226 ( 3.28 % of Total)
NUMBER OF BLOCKED CELLS = 6674 ( 96.72 % of Total)

Did you check your STL normals are pointing in the correct direction? This is a common issue.

Thanks for your reply. I checked the stl normals as you recommended and they were pointing in the wrong direction and I flipped them and problem solved.

Thanks a lot.
