Hi Foamers,

I am trying to represent the term tensor & grad(U), being both tensor and grad(U) order 2 tensors. I am considering this term as a source, however I do use neither Sp, Su or SuSp to represent it.

However, from a computacional point of view, is not better to discretize it using Sp, Su and SuSp. I tried

Sp (tensor & grad(U), tensor), but it gave me a error. How I can represent this term?

Regards,

António Martins

Hi titio
if you want to discrete the term in a explicit form, just calculate the value of your expression and add it to your equation. You don't have to use sp, su, susp.
The coefficient of is Sp is a dimensionedScalar or volScalarField, however tensor & grad (U) gives a volVectorField.That may be the problem.
