Hello SirMay you kindly assist me, I am struggling with creating a double pipe geometry ( concentric pipes).I am trying to create concentric pipes, however when I run my blockMesh file it gives me the below error. I have checked block numbering and vertices not sure what the issue is. May you kindly assist me, I can send my blockMesh File and the image of my geometry.Create timeCreating block mesh from "system/blockMeshDict"Creating block edgesNo non-planar block faces definedCreating topology blocks--> FOAM FATAL IO ERROR: Block hex (3 8 9 2 7 10 11 6) (100 40 10) simpleGrading (1(1) 1(1) 1(0.1)) has inward-pointing faces 4(3 7 6 2) 4(8 9 11 10) 4(3 8 10 7) 4(3 2 9 8) 4(7 10 11 6) file: /home/machine/OpenFOAM2006/machine-v2006/run/laminarpipeflow/system/blockMeshDict.blocks at line 90.

How to determine the arc coordinates to built perfect circle
Can we select any vortex point, which is passing from the arc?
while solving the problems given in video, i came to know that i have to draw a circle profile in openfoam. so when i was drawing that i written all the vertices but when i want to see that in parafoam, it not showing. what i have to do next ?
