I am trying DTCHull case in OF V.2206 Version 2.0. while running snappyhexmesh after executing toposet and refinemesh i am getting an error as shown in uploaded picture. it gives a message like cell513214 of level 0 uses more then 8 points of equal or lower level. if anyone have come across such an issue please tell the way to rectify this issue.
is this because of non gradual refinement between two layers, please enlighten me with the solution
OpenFOAM




commands in order of execution
blockmesh-surfacefeatureextract-toposet(1)-refinemeshdict-toposet(2)-refinemeshdict-toposet(3)-refinemeshdict-snappyhexmesh
this is the order i followed, please help me with a solution @Aabhushan if you ever come across such an error.
Thankyou,
Regards

Hi MS321,
Make sure you are giving the "refineMeshDict -overwrite" command every time you are refining mesh. Also, this tutorial requires you to run a series of toposet and refineMesh six times. Although it will work for just three times the mesh created will be very bad.

I am using OpenFOAM v9 and it's the exact same tutorial. It's working perfectly in mine. Give me some time I will try this in your OpenFOAM version and see if I can reproduce the error.
