Hello blacksquirrel,
can you please give me your mail id, so that i will send my mesh file via sendspace.

thanks,
Siva

Hello blacksquirrel,
I have up loaded the file in send space, I think you have received the email from send space.

please have a look and tell me what was wrong.

Thank you very much for your time.
Siva

Ok, I received your mesh. I've only used simple (rectangular) channels for my simulations, so now I'm guessing, too.

Somewhere you have to tell OpenFOAM that it needs to rotate patch ILR to match ILR_shadow.

You can try this:

transform rotational;
rotationAxis (1 0 0); //adjust this to your case
//rotationCentre (0 0 0);

If this doesn't work, then I'm clueless. I'm sorry.

Hello blacksquirrel,
Thanks for your reply, I want try the previous reply from you.
you said that we can create the cyclic BC using the createPatch utility.

I am bit confused to edit the createPatchDict.

can you please help me to edit.

after creating the wall boundary my boundary file look like this,

12
(
outlet
{
type patch;
nFaces 6400;
startFace 6276800;
}
inlet
{
type patch;
nFaces 6400;
startFace 6283200;
}
top2
{
type wall;
nFaces 16000;
startFace 6289600;
}
top1
{
type wall;
nFaces 2400;
startFace 6305600;
}
top0
{
type wall;
nFaces 8000;
startFace 6308000;
}
center1
{
type wall;
nFaces 16000;
startFace 6316000;
}
center0
{
type wall;
nFaces 8000;
startFace 6332000;
}
OR
{
type wall;
nFaces 16000;
startFace 6340000;
}
OL
{
type wall;
nFaces 16000;
startFace 6356000;
}
FAN
{
type wall;
nFaces 7200;
startFace 6372000;
}
IFR
{
type wall;
nFaces 8000;
startFace 6379200;
}
IFL
{
type wall;
nFaces 8000;
startFace 6387200;
}
)


in that I am able to see the "patch" to "cyclic" but how to do "wall" to "cyclic"


can you please guide me.


Thanks and Regards,
Sivakumar

Hi Guys,
I have solved the problem, Its simple issue.
I didn’t edit the 0 folder files according to my boundary file.
after editing the 0 folder files, now I am able to see the mesh in paraFoam.

Thank you very much for your help.

soon i will come with another problem.

thank you guys,
Sivakumar

please help me to sort out this problem,

And what are the further steps I need to follow?

Thank you,

Are you trying to lauch FluentMeshToFoam from your system folder?
That can explain that it cannot find the "controlDict" located in a "system/system/" folder. You have to lauch fluentMeshToFoam from the root of your case.

[syn1993530]

Thank you for your help.And I have lauch FluentMeshToFoam from my system folder.However, it still exist this problem.

Maybe my previous advice was not clear enough.
You cannot launch FluentMeshToFoam from the system folder. You have to launch it from the root of your case!
