Hello Foamers,

Now I am trying to do decomposepar .

The order is:
blockmesh
toposet
createpatch -overwrite
decomposepar

after this, the error appears.

--> FOAM FATAL IO ERROR:
size 3764160 is not equal to the given value of 216000

file: /home/...case.../0/ccz from line 18 to line 3811162.

From function Field<Type>::Field(const word& keyword, const dictionary&, const label)
in file /home/OpenFOAM/OpenFOAM2.1.1/src/OpenFOAM/lnInclude/Field.C at line 236.

FOAM exiting


I didn't meet the error before. but if I do this order:
blockmesh
toposet
createpatch -overwrite
snappyhexmesh -overwrite
decomposepar
Then it is OK.

Help!

Thanks.

This problem often happen when your variables files (in the "0" folder for example) come from another mesh.

Then the mesh has N cells and your variables files have Y cells. The decomposition cannot find the corresponding cells and crash


To solve this problem, look at your "0" file and find the problematic file (you might also want to check the hidden files).

The answer is in your post actually.

The "0/ccz" file has more cells than your actual cell number declared in the mesh.
