Laplacian error
 
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

Sorrr I meant this:

volVectorField lapU=fvc::laplacian(U);

Hi Mani,

What is the error message you got? Do you use the right field type and/or should you use fvm instead of fvc?
