WARNING: Non-manifold edge 55927 found

Hello,

I am trying to use coreform cubit to define materials, boundary conditions, and then mesh to utilize in OpenMC. The problem I’m having is that when I try to plot the dagmc geometry into OpenMC i get a lot of artifacts. below is what i see, it should be flat on the xz plane at y=0 but its not. If I move the y to 1e-8 it doesnt have the artifacts. some errors I get when plotting is the non-manifold edge. Could this be the problem or is there something else?

Hello @thallam,
could you please share the geometry that you are trying to export.

Here is the cubit file that is set up and meshed.

I have been doing some research and I have found a forum that suggest that the geometry is correct its just the plotter that is messing up because it is plotting on some of the triangle edges and that is what is causing this problem. could that be the case?

I am not familiar how to use the openmc package. Could you please share the python script to get the geometry plotted?
