I tried to write one application for post processing in openfoam where i need to compute integrals of the product of different pressure fields
I wrote it in my code this
pcorrMatrix[i][j] = fvc::domainIntegrate(pressurefield[i]&pressurefield[j]).value();

where pressurefield[i] and pressurefield[j] are different pressure fields
but I got this when I compiled the code


Foam::volMesh>’ is not derived from ‘const Foam:iagTensorN<Cmpt, length>’
pcorrMatrix[i][j] = fvc::domainIntegrate(pressurefield[i]&pressurefield[j]).value(); //Correlation matrix calculation L2 projection


any help for the solution of this problem.
Thank you very much.

Can you please post your code and error in code and also in full. It's hard to understand when we don't know how your pressureField has been defined and the error is not complete.
