I hope this message finds you well. I am writing to seek some problems into an issue I’ve encountered with the 3D mesh in our current project.
Recently, I noticed that the 3D mesh is behaving unusually in certain sections of our model. The irregularities seem to be affecting the accuracy of our simulations, and I am concerned about the potential impact on our results. Could anyone provide clarity on why this might be happening? Are there specific parameters or settings that might be contributing to this anomaly?
can you elaborate what you actually mean? I see that the meshes in your picture look funny, but it’s not clear to me whether that’s the mesh or a visualization artifact. But then I’m also not sure how exactly you generated these pictures or what they are supposed to show.

@Xiao This is a visualization artifact. In order to visualize a 3d mesh the way you show it, Paraview (or any other program for that matter) needs to put a cut plane through the mesh. If that cut plane happens to coincide with a face between cells, some nodes will be on one or the other side of the cut plane just based on round-off error. This results in strange artifacts like the one you show. You can sometimes get a better visualizing by moving the cut plane by a small amount, but it does not always work.
In the end, these are just artifacts of what Paraview shows for the mesh. The solution you get to see is unaffected. In other words, if you only show the solution, you should not see any artifacts.
