chtMultiRegionSimpleFoam: strange error

samiam1000 · October 9, 2013, 11:22

Dear all,

trying to run my chtMultiRegionSimpleFoam simulation, I get this error:

Code:

The point is that it does not suggest me which is the corrupted file. Any idea? Is the error supposed to be in the domain3 region? Or domain3 is ok and I have to look in the next ones?

Thanks a lot,
Samuele

Hi Samuele,

Try this:

Code:

find . -name ".T"

It will tell you where the files named ".T" are located.

By the way, on Linux, files that start with "." are usually considered as hidden files. To see then, use the "-a" option with "ls" or "ll", for examples:

Code:

ls -a
ll -a
ls -la

The two last ones should be the same, because "ll" is an alias (when defined as such), as proved by this command:

Code:

alias ll

Best regards,
Bruno

I Bruno,

the point is that there was not such a file :-/..

..I've changed the folder case name and not I don't have this error.

But I have this new one:

Could you help?

Thanks a lot,

Hi Samuel,

the first error is nice - never seen that befor.

The last error "Floating Point exeption" occure if you are dividing by Zero.

Check all your BC and set always the "value uniform X" keyword.

But hmmm ... it seems that you get the error while updating the thermodynamics. Maybe when the constructor is selected.

But first check my first hint.
Your meshes are okay?
Boundary files okay too?

Regards
Tobi

samiam1000 · October 14, 2013, 08:49

Dear Tobi,

thanks for answering. Well, let me have a look at all the BC. Anyway, I am pretty confident it is ok! As far as the mesh is concerned, it should be alright.

I'll give you a feedback, soon.

Thanks a lot,
Samuele

samiam1000 · October 21, 2013, 06:39

Dear Tobi,

I have checked all the BC and I have done some modifications.

The point is that now I have done a small step ahead, but there still is something wrong:

Any idea about this `new' (for me) error?

Hi,

first of all post the p_rgh file (0/fluid/p_rgh).
And the second error (Segmentation fault) is in your domain5. You have an error there.

Hi Tobi,

following your advice, I solved an error, but I now get this message:

Code:

Attempt to cast type calculated to type compressible::turbulentTemperatureCoupledBaffleMixed

However, I think that my BC are properly set. Where may the error be, according to you?

Thanks a lot,
Samuele

Tobi · October 21, 2013, 12:02

Hi

Code:

       domain5_to_fluid
        {
            type            mappedWall;
            nFaces          3997;
            startFace       49350;
            sampleMode      nearestPatchFace;
            sampleRegion    fluid;
            samplePatch     fluid_to_domain1;  // should be fluid_to_domain5 
            offsetMode      uniform;
            offset          (0 0 0);
        }

The other error... can you give me more information?

samiam1000 · October 21, 2013, 12:12

Yeah: it's right.

        }
    }

Is there something strange?

Tobi,

I have solved that problem, changing the BC. But I still have troubles: now I get this message:

The point is that I don't have any h file, anywhere.

Any idea about this?

Tobi · October 23, 2013, 08:03

Hi,

the T-file Looks good.
The Problem in the cht solver is always that the Domains are related to each other and the Problem could be in both. I worked a Long time with the cht but at the Moment I am not working anymore with it.

Therefor I am getting rusty in the error Messages

Is it possible to upload you 0 Folder and the constant Folder, best way would be the whole case.

Maybe its not possible for you (due to secret) it would be very good to have the 0 Folder and the constant/***/polyMesh/boundary files to have a look at the whole case. It would be the best way to give you a correct answer.

Otherwise you should always get more Information

So if you solving "domain1_to_fluid" it is interessting to have the related files of both Domains.

For your Problem it could be possible that you use "fluidThermo" in the T file for your solid Domain. there should be "solidThermo".

Regards Tobi

samiam1000 · October 23, 2013, 09:20

I can share the case with you via Skype. I have tried to contact you there.

If you are online, please let me know. Otherwise, please write me at samuele.zampini@polimi.com and I'll send you tha case.

Thank you very much,
Samuele

Tobi · October 23, 2013, 09:39

Hi Samuel,

i am online today evening (in 2 hours).
Otherwise you can send me the case Tobias.Holzmann@Holzmann-cfd.de

Hi,

i experienced such a problem before, already today. i found that my mistake was in changeDirectoryDict where i wrongly wrote than name of interface patch, i simply change uppercase letter to lowercase. that's it.

i hope it will be helpful for you.

samiam1000 · October 23, 2013, 12:24

I'm pretty sure about the patch names, but I'll check them again!

Thanks!

Hi,

1. your changeDict has a wrong entry like ahmed mentioned in your domain2

Code:

            domain2_to_fluid
            {
                type            mappedWall;
                nFaces          3997;
                startFace       49350;
                sampleMode      nearestPatchFace;
                sampleRegion    fluid;
                samplePatch     fluid_to_domain1;  //domain2
                offsetMode      uniform;
                offset          (0 0 0);
            }
        }

2. wrong schemes and solution for your solids

3. wrong changeDict in domain1

Code:

    T
    {
        internalField   uniform 298;

        boundaryField
        {
                    empty_2-packs
                    {
                        type            symmetryPlane;
                    }
                    wall_packs
                    {
                        type            zeroGradient        // forget ";"
                    }
                    domain1_to_fluid
                    {
                                type            compressible::turbulentTemperatureCoupledBaffleMixed;
                                value           uniform 298;
                                neighbourFieldName T;
                                kappa           solidThermo;
                                kappaName       none;
                    }
        }

4. after changeDict on domain2 there are still one error in your "0/domain2/T" file:

Code:

   empty_2-packs
    {
        type            symmetryPlane;
    }
    wall_packs
    {
        type            zeroGradient 
    } 

    domain1_to_fluid 
    { 
       type compressible::turbulentTemperatureCoupledBaffleMixed;
        value           uniform 298;
        neighbourFieldName T;
        kappa           solidThermo;
        kappaName       none;
    }
    domain1_to_fluid                      // wrong - not needed
    {
        type            calculated; 
        value           uniform 0;
        neighbourFieldName T;
        kappa           solidThermo;
        kappaName       none;
    }

After the changes you will get the following output:

ExecutionTime = 5.9 s  ClockTime = 6 s

- the second iteration is bad but I switched off the turbulence modelling and do not check the BC.

Have fun and good luck.

Tobi

By the way, on Linux, files that start with "." are usually considered as hidden files. To see then, use the "-a" option with "ls" or "ll", for examples: Code: ls -a ll -a ls -la The two last ones should be the same, because "ll" is an alias (when defined as such), as proved by this command: Code: alias ll Best regards, Bruno __________________ OpenFOAM: FAQ \| Getting started Forum: How to get help, to post code/output and forum guide Read this before sending me PM

The last error "Floating Point exeption" occure if you are dividing by Zero. Check all your BC and set always the "value uniform X" keyword. But hmmm ... it seems that you get the error while updating the thermodynamics. Maybe when the constructor is selected. But first check my first hint. Your meshes are okay? Boundary files okay too? Regards Tobi

Anyway, I am pretty confident it is ok! As far as the mesh is concerned, it should be alright. I'll give you a feedback, soon. Thanks a lot, Samuele

samiam1000 Senior Member Samuele Z Join Date: Oct 2009 Location: Mozzate - Co - Italy Posts: 520 Rep Power: 20	Hi Tobi, following your advice, I solved an error, but I now get this message: Code: Attempt to cast type calculated to type compressible::turbulentTemperatureCoupledBaffleMixed However, I think that my BC are properly set. Where may the error be, according to you? Thanks a lot, Samuele

Tobi Super Moderator Tobias Holzmann Join Date: Oct 2010 Location: Bad Wörishofen Posts: 2,716 Blog Entries: 6 Rep Power: 53	Hi, the T-file Looks good. The Problem in the cht solver is always that the Domains are related to each other and the Problem could be in both. I worked a Long time with the cht but at the Moment I am not working anymore with it. Therefor I am getting rusty in the error Messages Is it possible to upload you 0 Folder and the constant Folder, best way would be the whole case. Maybe its not possible for you (due to secret) it would be very good to have the 0 Folder and the constant/***/polyMesh/boundary files to have a look at the whole case. It would be the best way to give you a correct answer. Otherwise you should always get more Information So if you solving "domain1_to_fluid" it is interessting to have the related files of both Domains. For your Problem it could be possible that you use "fluidThermo" in the T file for your solid Domain. there should be "solidThermo". Regards Tobi
