For face meshing it must be,first, determined the nodes of all its edges. If i want to determine additional nodes for different distribution of face mesh must be on face edge or on other edge type?
With other words, i must "split" the face at location where i want to add nodes so that to appear edge? |

Yes. Split your surface. you will introduce new topology (edge-point or surface) which can be used as source in a size fonction

Ok.Thanks. But after meshing can i delete all these inner topologies so that ramain only the mesh? I want this i order to use this mesh face as sourse face in "cooper algorithm" for 3d meshing but if sourse face has inner topologies connot work.

if you split your surface into 2 surfaces, than take the 2 surfaces as source for cooper

Yes but if split partially the face (hard edge), i have not 2 faces. I have again 1 face with inner edge which can connect or not with outer edges.
Is there any way from this? Have you man to talk more easy? |

hard edges are supposed to be fixed....
But you can try. Why don't you want to split your face into 2 surfaces? I don't understand what you mean

no msn
did you try to mesh your surface with an hard edge?

Yes, the mesh of face is ok. Near hard edge i have dense mesh as i want. But i can not use this face for cooper alg. due to hard edge. Can i have the same mesh of face in face without hard edges(splits)?

yes it failed because of hard edge.. that's why you need to fix it.
Tell me why you don't want to split your surface into 2 surfaces? Sans titre.jpg

Because, i want to distibute nodes at specified length of edge.
Look. I have make a NACA airfoil and i want to run it in transonic regime. I must put, general, few elements (less computational cost) but in region where appear the shock i want dense mesh. Therefore, i need dense mesh only near of hard edge. In residual face the pave method must do its work. Ok. finally i will do as you talk(split at two faces) but i believe that there is a way to disconnect mesh by topology so that to move only mesh in same face without hard edges. Is there? |

This is the 2d mesh. The hard edge is appear in above face.

Then split your surfaces so that your "shock-line" divide a surface into 2 surfaces.
For example like that Sans titre.jpg

Finally, it is working! The cooper scheme work with this way. Look the picture in witch i have split the face in three sub faces.
