I get the error of segementation fault.
May be I am doing something silly please correct me.

Pratap

Am I correct when I say that you are
trying to mesh the 'bluffbody'?

Why?

[pratap]

Nope I am not meshing the bluffbody.
Pratap

You are trying to use a "prism" as a block shape. All block must (nominally) be hex - use double vertices in hex definition instead.

Change the value of 4 into 7 in the thirdface

i use the above block mesh dict file for naca0012 airfoil case... i am getting wrong meshing for these vertices at the leading edge....please correct it...

[naveen]

HI EVERYONE


MY SELF NAVEEN
i am new to openfoam cfd software i am not able to solve the naca0012 airfoil case in openfoam ..can u please help me regarding this and if u r having any tutorial based on openfoam please send me...

[naveen]

hi every body

can u send me a naca 0012 tutorial to solve in openFOAM...

Hallo,

the case you are trying to solve won't work because the blocks intersect each other. I see, that you have a big block with a little block inside. you cannot create the big block an the the little one inside. you will have to split the big block into three blocks.

also add the following vertices at the end of your list

(14 22.5 0) //Vertex 14
(14 22.5 1) //Vertex 15
(18 0.5 0) //Vertex 16
(18 0.5 1) //Vertex 17

then you'll have all in all 4 blocks

(0 5 6 4 7 12 13 11)(14 1 1)
(5 2 16 6 12 9 17 13)(166 1 1)
(4 6 14 1 11 13 15 8)(166 44 1)
(6 16 3 14 13 17 10 15)(14 44 1)

Not sure if this is right, but the nodes of the blocks have to match the nodes of the neighbour block.

....and hey, VIJAYAKUMAR R, not sure what you try to simulate with this. maybe you can explain al little more detailed next time.
