Segmentation fault when running dieselFoam or dieselEngineFoam in parallel
 

Hi everyone,

It seems that there is some kind of a bug when running dieselEngineFoam in parallel. I've just tested it with the 1.5-dev version and it appears that this application gives a segmentation fault as follows:


I've observed the same problem with dieselFoam on the aachenBomb tutorial case.

These two applications work on serial. Other applications (icoFoam and engineFoam) work fine on the same cluster.

If someone can help me, it would be great.

Francesco.

Here is an input:

I've removed all occurence of the spray inside the application and now it does not give me a segmentation fault anymore.

Is it possible that the dieselSpray library could be a problem here?

Francesco.

I have similar problems with another solver
 

It seems that your problem parallels (pun intended) a similar problems with another solver (http://www.cfd-online.com/Forums/ope...ngianfoam.html) post 13 that I had. Did this error get resolved in your case? Without changing to another version of OF.

check your constant/sprayProperties and change
 

check your constant/sprayProperties and change

interpolationSchemes
{
U cellPointFace;
rho cell;
p cell;
T cell;
}


to

interpolationSchemes
{
U cell;
rho cell;
p cell;
T cell;
}

Hope it works

hi mehdi

it really works

by the way, do you know the reason why it doesn't work for cellpointface?

however, both cell and cellpointface work well in parallel in foam-extend 3.2, when only cell suport the parallel running in foam-extend 4.0, can you give me
a hint why this happens?

moverover, when i use cell, the caculation always crashes for temperatue lower than 200k at the beginning of injection, i use dieselEngineFoam

thanks
