Hello
For a good quality tetrahedral volume mesh on a cylinder, is it compulsory to mesh the outer faces of the volume as Tri-Pave? or is it fine to mesh the faces with Quad-pave..Please expalin Thank you |

for a cylinder, I think you can afford to mesh it with hexa (cooper).
Mesh one cap surface first (with pave)

Hi,
If you would like to fill the cylinder with tetrahedral you have another option. You can mesh surfaces with quads then create one set of pyramids and then fill with tets. Hope this helps |

Thank you for your replies
Well, the following picture shows the geometry. It's hard to mesh it via hexahedral scheme hence i would like to mesh it via tetrahedral scheme but the quality of the mesh is very low via tetrahedral. Could you explain how can i approach this problem. Thanks |

*Mesh cylinder first (one cap with quad). *Then split the block, like I did for instance. *Mesh the yellow volume with cooper (mesh source face in front of you) *Then mesh the orange and pink volumes. Source faces are the one on the top of volume

just wanted to know, how did u split this volume?
You first made vertices, then arcs and then from arcs u made face and split? |

The split operation as u mentioned, gives an error. Can u tell me the reason why is it doing like this? I created another thread:
