Hi all,
I am new to openFoam. I am having the same problem as described above in threads. below is my blockMeshDict file. Basically my geometry is cuboid of dimension 20*10*1 (all dimensions are in mm). Within it is enclosed two concentric circles of radius 4mm and 2mm. Basically the concentric circles are blocked according to hagen poiusselii flow. the circles are at the centre of cuboid and origin starts from there.

Plz suggest me where is the error???

[alexB]

Hi Ajay,

could you draw a sketch of your geometry and post your log with the error message?

regards
Alex

[AJAY BHANDARI]

Hi alex,
First of all thanks for your reply. i have drawn a rough sketch of my geometry with dimensions. I am attaching it with this. Its basically a cuboid of dimension 20mm*10mm*1mm. with two concentric circles within it one of radius 2mm and other of radius 4mm. I have kept front and back faces empty because i want a 2D simulation. The circles back face and front face images are also attached for clearity. Basically it will become annular cylinder when viewed in 3D. I have already posted my BlockMeshDict file. Its showing error that face 0 in patch 4 does not have neighbouring face (26 27 28 29). Please suggest now. Any more information you want about the geometry please tell.

[AJAY BHANDARI]

Hi Alex,

One more thing i want to tell is that basically i am simulating a fluid flow through a body tissue which is basically a porous media. the two concentric circles are basically tumor and necrotic core which are different regions and rest all space that is cuboid excluding the two circles is normal tissue. all the three regions have same porosity but different transport properties. I am using porousSimpleFoam for this. In that I have changed the Peqn.H file and added some source and sink terms which have lot of constants and all are declared in transport properties. All the three regions which i have described above have different transport properties.
My problem is can u tell me how to assign different transport properties for these three regions which u can see in my figure attached in previous post and where??? Any kind of help will be appreciated..If anything u want to know more about this problem plzz let me know....

Regards
Ajay

[alexB]

Hi Ajay,

I see one problem...

you have just defined 2 empty faces for frontAndBack, but if you try to set up a two-dimensional every defined block has two empty faces which have to be defined properly.

regards
Alex

[AJAY BHANDARI]

Hi Alex,
Thanks for your reply again. But i couldn't get that. Where i have to define that block empty faces??? Could you please elaborate???or point out in the BlockMeshDict file.

Hi,

you only defined 2 empty faces when you really have 2 empty faces per block created, in your geometry it would be like 26 empty faces I think... I haven't checked the whole blockMeshDict definitiion, but at least this is an important mistake... Correct it and try again!

Best regards,

Alex

Hi alex,

Thanks for your reply. error has been removed. I did exactly as you suggested and created 26 empty faces. But unfortunately one more error is coming now. See

But i want former dict file So plz suggest what should i do???

[alexB]

As written in another thread

You have to define your blocks in the correct way.
see http://cfd.direct/openfoam/user-guid...#x25-1420005.3

"Each block has a local coordinate system that must be right-handed. "
If not the volume of the block would be negative. (first problem solved)

next problem would be, that your grading from on block to the other wouldn't fit, because the grading for each block is oriented regarding to this local coordinate system.

[AJAY BHANDARI]

Hi alex,

Thanks for your reply. I have read the user guide. I tried but failed. Basically I want 192 cells in x direction and 96 cells in y direction with spacing between each cell 0.104*0.104mm. Do i have to divide these cells by the no of blocks in each direction?? Plz suggest...

Regards
AJAY

[alexB]

Hi Ajay,

I see that I have to explain my last quote.

"Each block has a local coordinate system that must be right-handed. "
If not the volume of the block would be negative. (first problem solved)

I took a short look on your dict and the blocks seem to be fine... (no negative volume)

next problem would be, that your grading from on block to the other wouldn't fit, because the grading for each block is oriented regarding to this local coordinate system.

I guessed that this will be your prob, so I had underlined it before.

I give you a new quote from the user guide:

• the direction is described by moving from vertex 0 to vertex 1;
• the direction is described by moving from vertex 1 to vertex 2;
• vertices 0, 1, 2, 3 define the plane ;
• vertex 4 is found by moving from vertex 0 in the direction;

While reading this, take a look at the picture in the guide.

For example your first block has the x-direction from point 1 to point 2 .
But your second block has the x-direction from point 1 to point 5 .
That is generally not a problem. But your grading leads to trouble.

You have to choices:
Define your second block like "hex (5 6 2 1 ....)"
Or change the grading from (15 10 1) simpleGrading (0.104 0.077 1) to (10 15 1) simpleGrading (0.077 0.104 1)

I hope it helps
Alex

[AJAY BHANDARI]

Hi alex,

Thanks for your reply and for answering to my posts. I have understood what you are trying to say and i even changed the block numbering and simple grading as you said. I did many trials but its not working. Its giving same error. Could you please spend some of your precious time on my blockMesh dict file and tell me exactly where to change the grading or numbering of block. Here's the blockMesh dict file.

Basically i want total 192 cells in x dirn and 96 cells in y dirn. and spacing between each cell to be 0.104*0.104mm. How should i divide them in each block and where i should change????

Hi Ajay,

in this post you say the last dict works.

But i want former dict file So plz suggest what should i do???

so start from that dict and change it in little steps... so you can see where it goes wrong.

And I have to ask one question:
what do you mean with spacing between the cells?

and spacing between each cell to be 0.104*0.104mm. How should i divide them in each block and where i should change????

regards
Alex

Hi alex,

Sry for my late reply. Actually i was wrong 0.104*0.104 mm is the cell dimension in x and y dirn. but in simple grading it is the cell expansion ratio so it will remain same that is (1 1 1) only. I tried changing no of grid points in x and y dirn step wise as you said . I did this

hex (1 2 3 4 13 14 15 16) porosity (15 10 1) simpleGrading (1 1 1)
hex (1 5 6 2 13 17 18 14) porosity14 (10 15 1) simpleGrading (1 1 1)
hex (2 6 7 3 14 18 19 15) porosity15 (15 10 1) simpleGrading (1 1 1)
hex (3 7 8 4 15 19 20 16) porosity16 (10 15 1) simpleGrading (1 1 1)

By changing first three it didn,t give any error but when i change fourth one it gives error inconssitent no of patches between blocks 0 and 3 . So i think error is in fourth step... Can you help me out????

[alexB]

looks fine so far,

perhaps test, hex (4 3 7 8 16 15 19 20) porosity16 (15 10 1) simpleGrading (1 1 1)

Thanks alex... it worked Thanks for your consistent help...

Hi,

I generated an axis-symmetric mesh with success. However, at one of the faces declaration the vertices are not clockwise oriented. All the other faces are clockwise oriented, but if I put this one as well it complains about having no neighbours. Then, when I inverted the order from clockwise to anti-clockwise it worked! Why?

The face I am referring to is the face (3 5 2 3) from outlet.

In my opinion, it should be (3 2 5 3).

Here is my file:

convertToMeters 0.001;

vertices
(
(0.0 0.0 0.0) //vertex 0
(24.904867 2.178893 0.0) //vertex 1
(24.904867 2.178893 137.0) //vertex 2
(0.0 0.0 137.0) //vertex 3
(24.904867 -2.178893 0.0) //vertex 4
(24.904867 -2.178893 137.0) //vertex 5
);

blocks
(
hex (0 4 1 0 3 5 2 3) (20 2 100) simpleGrading (1 1 1)
);

edges
(
);

boundary
(
air
{
type patch;
faces
(
(0 4 1 0)
);
}
outlet
{
type patch;
faces
(
(3 5 2 3)
);
}
fixedWall
{
type wall;
faces
(
(1 4 5 2)
);
}
front
{
type wedge;
faces
(
(0 1 2 3)
);
}
back
{
type wedge;
faces
(
(3 5 4 0)
);
}
axis
{
type empty;
faces
(
(0 3 3 0)
);
}
);

mergePatchPairs
(
);

Any feedback I appreciate.

Thanks in advance.

Hi Lisandro,

I think you shouldn't let collapse one of the first 4 point, as they are used to define your local coordinate system of the block.

Perhaps it solves your prob.
