I have tried several blockMesDict files trying to make a cylinder using arc. blockMesh seems to go fine, but the arc is not visible in paraview (version 3.6.1). Anyone experienced this ? I used an example from the user manual so I recon the use of arc should be ok.

I had the same problem with paraview 4.1.0
It is at the moment just a 1 cell try. BlockMesh code runs but it doesn't show any arc. Code:
L 288; D 88; R 100; B 722; C 222; alpha 35.0; CapL 50; Dd 50; nzp 50; zp 50; //declaración de distancias Fd #calc "10*$L"; Bd #calc "20*$L"; Ud #calc "8*$L"; Ax #calc "$Fd$CapL"; Bx #calc "$Fd+$R($R+$CapL)*cos(45.0)"; Cx #calc "$Fd+$R$R*cos(45.0)"; //Dx #calc "$Fd+$R"; //Ex #calc "$Fd+$R+$B"; Cy #calc "$Dd+$R+$D"; Dy #calc "$Dd+$R+$D+($R+$CapL)*sin(45.0)"; //Gy #calc "$Dd+$L"; Hy #calc "$Dd+$D+$R+$R*sin(45.0)"; //Ly #calc "$Dd+$L+$CapL"; convertToMeters 0.001; vertices ( ($Ax $Cy $nzp) ($Fd $Cy $nzp) ($Cx $Hy $nzp) ($Bx $Dy $nzp) ($Ax $Cy $zp) ($Fd $Cy $zp) ($Cx $Hy $zp) ($Bx $Dy $zp) ); blocks ( hex (0 1 2 3 4 5 6 7) (1 1 1) simpleGrading (1 1 1) //0 ); edges ( arc 1 2 (#calc "$Fd+($R$R*cos(20.0))" #calc "$Cy+$R*sin(20.0)" $nzp) ); boundary ( ); mergePatchPairs ( ); Moreover, after perform checkMesh got 1 failure: Code:

Your explanation has been very useful because I realized that just changing the number of cells per each direction (x' y'), arcs are drawn. so I changed like this: hex (0 1 2 3 4 5 6 7) (20 20 1) simpleGrading (1 1 1) //0 Thanks a lot. Best regards Ivan

That affects only the way the cells are distributed along their directions. I hope you wanted to write this: Code:
hex (0 1 2 3 4 5 6 7) (20 20 1) simpleGrading (1 1 1) //0
