Quick question: Have you already searched here on the forum, namely in the sub-forum "blockMesh"? OpenFOAM Native Meshers: blockMesh

Dear wyldckat,

yes i searches a lot for it. i found my way to do it. but I'm searching now for better or easier ideas. I'll share my mesh in another post or may be in a blog. because a tube must be done from cylinder then split it to solid part and flow part as my way.

thanks for your reply

Four quarter domains with thickened arcs above that will work.

Quarter domains for pipe and arcs for pipe thickness.

Dear Ahmed,

You refer to User guide for making wedge type mesh and your domain in to two blocks as shown in the attachment.

Also refer this code for axisymmetric pipe (Just for example) using single cell thickness. For multi cell, use curved surfaces defined by arc.

Note: Create your own vertices(Use paraFoam block to understand the positioning)

Code:
vertices        
(
    (0 0 0)                          //0
    (0 0.6 0.020943951)              //1
    (0 0.6 -0.020943951)             //2
    (30 0 0)                        //3
    (30 0.6 0.020943951)            //4
    (30 0.6 -0.020943951)           //5
    (0 180 6.283185307)             //6
    (30 180 6.283185307)           //7
    (30 180 -6.283185307)          //8
    (0 180 -6.283185307)          //9
);

blocks          
(
    hex (0 3 3 0 1 4 5 2) (15 1 5) simpleGrading (4 1 1)
    hex (1 4 5 2 6 7 8 9) (15 1 9) simpleGrading (4 1 5)

);
