Problem of crossed cells while visualizing 3D mesh in 2D using ParaFoam
1 Attachment(s)
Hello All,
I am trying to visualize the 3 D mesh around an object (for ex aerofoil). I took the object (aerofoil), slice it, then put the internalfield on, and then hide the block. But instead of getting clear cells the cells appeared to be crossed. By looking at the post I even tried the filter "ExtractCellsByRegion", but this also haven't helped. The mesh of crossed grid is attached herewith. Thanks a lot! |
(Very likely) Nothing problematic related to the mesh itself. This is just visualisation itself provided by Paraview.
checkMesh utility is your friend to tangibly quantify your mesh quality. |
May thanks HPE for the prompt reply. But I was just exploring the better way of visualizing the mesh, so that it looks good. Thanks again for the help !

Paraview will visualize using tets by default. The easiest way to visualize the cells (assuming that you are using predominately hexes) is to : load paraview with the "useVTKpolyhedron" box checked. Then you can take a slice through your domain (make sure it's through cells, not on cell faces), and uncheck the "triangulate slice" option for the slice. Then look at the slice as a surface with edges or a wireframe.

Many thanks Caelan for your help. I am using paraview 5.01, and could not find the "useVTKpolyhedron" although tried to see some of the tutorials also but could not find it. I am very new to the parafoam so sorry for asking this naive query. It will be a great help if you could share the screenshot of the "useVTKpolyhedron".
Thanks again! |

Hi,
ParaView automatically triangulates the slice. Deselect "Triangulate the slice" and select "Crincle slice" in the properties panel to visualize the mesh. Best, Mikko |
Hello Mikko,
Wow! it worked...Thanks a lot Thanks a lot! |
