| Summary | 0002350: Creating a field that is cache-able with postProcess fails | ||||
| Description | The "grad(U)" function for postProcess throws out warnings when it attempts to calculate for more than one time directory, e.g. Executing functionObjects --> FOAM Warning : From function bool Foam::functionObjects::regionFunctionObject::store(Foam::word&, const Foam::tmp<T>&, bool) [with ObjectType = Foam::GeometricField<Foam::Tensor<double>, Foam::fvPatchField, Foam::volMesh>] in file /home/ubuntu/OpenFOAM/OpenFOAM-4.1/src/OpenFOAM/lnInclude/regionFunctionObjectTemplates.C at line 61 Cannot store cache-able field with the named used in the cache. Either choose a different name or cache the field and use the 'writeObjects' functionObject. --> FOAM Warning : functionObject grad: Cannot find required field U | ||||
| Steps To Reproduce | run cp -r $FOAM_TUTORIALS/incompressible/simpleFoam/pitzDaily . blockMesh simpleFoam postProcess -func "grad(U)" | ||||
| Tags | No tags attached. | ||||

Currently the 'grad' functionObject can only be used if the result is explicitly named differently to the default due to interference between the caching of gradients and the post-processing fields. I am testing a work-around for this in OpenFOAM-dev. |

This issue should be resolved by commit c0a950c5c678b4a47e749a201527fc566f849be8 in OpenFOAM-dev but more testing is needed befor committing it to OpenFOAM-4.x. |
