CFD Online Discussion Forums - "--> FOAM FATAL ERROR:" by post processing by rhoPimpleFoam

- I have created source codes to compile and use the lib in the post processing. I am using OpenFOAM-v1612+

- After investigations the error appearing by reaching this part of the code, where `Ru1` is volTensorField

Code:

volTensorField Ru1( IOobject("Ru1", runTime.timeName(), mesh, IOobject::NO_READ, IOobject::AUTO_WRITE), mesh, dimensionedTensor("zero", dimensionSet(1, -1, -3, 0, 0), tensor::zero));

Code:

volVectorField divRu1 = fvc::div(Ru1);

- By using `rhoPimpleFoam` in post processing , i am getting always the below error , when i am using the `fvc::div()` function for volTensorField or volVectorField :

- any suggestion or help would so appreciated.
