Laplacian calculation
 

Hi,

I want to calculate d2U_i/(dx_j.dx_j) (j=1,2,3, i.e. summation convention). When I use:

volTensorField lapU=fvc::laplacian(U);

The code gives me an error. Does Anyone has an idea about its implementation?

Thanks in advance
Mani

Sorrry, I meant this:

volVectorField lapU=fvc::laplacian(U);

Hi,

Please say what the error is, otherwise it's a bit difficult for someone to answer...
