After running the sonicFoam/forwardStep case, I was interested to see how well the shock could be resolved by interpolating the old solution onto a finer mesh. Using icoFoam/cavityFine as an example, I increased cellDensity in both i and j directions, to 2i+1, 2j+1, then adjusted startTime to 10, then mapFields returned:

Source mesh size: 5250 Target mesh size: 21483


Consistently creating and mapping fields for time 10

interpolating p


--> FOAM FATAL ERROR :

FOAM exiting

Any information concerning the cause of the problem and the means of resolving it would be much appreciated... the error message gives me no clues.

Thanks,
John Van Norman

I get a similar error when running mapFields. I have just like you, only refined my mesh and want to map a coarser solution to a finer mesh. I get the following with the flag "-consistent"

--> FOAM Warning : treeBoundBox::treeBoundBox(const pointField& points) : cannot find bounding box for zero sized pointFieldreturning zero
Caught arithmetic exception

and then the output from gdb is:

#4 in Foam::meshToMesh::calcAddressing () from /users/tfd/f98faka/OpenFOAM/OpenFOAM-1.1/lib/linuxAMD64Opt/libsampling.so
#5 in Foam::meshToMesh::meshToMesh () from /users/tfd/f98faka/OpenFOAM/OpenFOAM-1.1/lib/linuxAMD64Opt/libsampling.so
#6 in mapConsistentMesh ()


However, if I run without the -consistent flag, it runs ok, but doesn't do anything, that is I get no new directories in the directory with the finer mesh.

Heya,

John: you have probably hit a boundary condition that the mapFields does not know about - could you have a look at the fields you're trying to map and tell me what boundary conditions you are using. Not a disaster, you'll just need to re-link the mapFields with some additional libraries (the one including the fvPatchField type you need). Could you try re-running the application under gdb and post the trace-back, e.g.:

gdb mapFields
r root1 case 1 root2 case2

where roots and cases are what you've used with the original mapFields

When it falls over, you'll (probably) be able to type "where" which will produce the info

Fabian: Hmm, is it possible that one of your meshes has no points in it? This is a failure to build the search trees, which means something is probably wrong with the mesh. Try running checkMesh on both meshes.

Also it is helpful to run with

setenv FOAM_ABORT 1

in your .cshrc (or equiv for .bashrc). This will cause OpenFOAM to abort (and produce a coredump) instead of exit.

I ran the same case with FOAM_ABORT 1 under gdb, with the same results. No stack or core dump, what am I doing wrong here? The fields are mapped (I think) from the same as in sonicFoam/forwardStep. Shall I forward the ~constant/* stuff to you? Perhaps my lack of understanding of OOP is the problem.
Thanks,

Hi John,

if you have the FOAM_ABORT environment variable set (in OpenFOAM1.1) you should get the message

FOAM aborting (FOAM_ABORT set)

Abort (core dumped)
Exit 134


and as long as you don't limit the coredumpsize you should get a core. (or you can run it inside gdb right away)

I set FOAM_ABORT 1, then ran mapFields under gdb and got the following:

I'm not sure what this means, besides that libc.so.6 is problematic. I have the linux version of OpenFOAM, but my distro (FC3) is the AMDx86_64 and I did not install every package. Think this might be the cause?

Forgot you were running on the AMD64 where traceback does not function properly. It should have printed out all the functions called upto the error.

Does the tutorial showing mapping work? Check what your case is different and work your way back from that.

hello,

from your log, you are not in cavityFine dir. Try "cd cavityFine" and after "mapFields cavity"
if you don't want to be in cavityFine dir, use the -case option.

Dear OliverG thanks for your answer
i did what u said but i cant mapFields cavity to cavityFine i thinks if i write here what i did step by step its better
the question is I CANT MAPPFIELDS CAVTIY TO CAVITYFINE AND NEED HELP?

i did:
1.copy cavity file to home/ashkan-2.1.0/run from openfoam tutorial
2.open terminal in Ubuntu and and make a directory by name cavityFine
3.copy cavity sub directory (0 and constant and systems) to cavityFine directory
4.change mesh resolution in cavityFine directory (constant/blockMeshDict)
5.go to cavityFine directory in Terminal
6.type "mapFileds OpenFOAM/ashkan-2.1.0/run/cavity"
and the below error appeared

hello ashkan,

* after step 4, you should create the mesh again, so use blockMesh again.
* step 6: try mapFields ../cavity
(or mapFields -case /home/ashkan/OpenFOAM/ashkan-2.1.0/run/cavityFine /home/ashkan/OpenFOAM/ashkan-2.1.0/run/cavity if you use the full path).

Hi all,

I am running a 2D cavity simulation (3D region with spanwise cross section all the way across) I want to map these results into a 3D cavity flow (essentially a channel flow with a box cut into the middle of the bottom surface of the channel).

When I try to run mapFields to map the 2D cavity results into the 3D cavity it does not create a 0/ directory (and of course, no files with it). However, there are no error messages and the output message reads as follows:

Hello,

I am having a similar problem as you describe. I do a simulation
in an empty box with blockMesh, then I want to map the fields
to the same box with a finer mesh done with snappy. This time there is an obstacle in the box, so an additional patch. When I run the mapFields I do not get any output either.
Source mesh size: 500000 Target mesh size: 919306


Mapping fields for time 0


End

Did you find out what was the problem in your case?
I tried indicating the patchMap ( );
and cuttingPatches ( ); in mapFieldsDict, but
nothing seems to work, and no error messages of any sort.

Thanks heaps in advance for any help on this.

Carlos

I think this can happen if you have already data in the target time directory. You can solve this option, to map it to a time-folder with some original files (like you have in 0/). If these files are empty, except for boundary conditions and uniform internal field, there is no mesh-information stored, and you should be able to use mapFields.
