Hi Timucin,

It seems that you are a bit confused.

Some info that might help clarify things for you:

n*n does not equal (1 0 0 1 0 1).

(1 0 0 1 0 1) is the identity tensor in symmetric...

"sqr" means square i.e. "sqr(n) = n*n"

"valueFraction = sqr(n)" means fixedValue in the "n" direction and fixedGradient in the two orthogonal directions.

Hi Timucin,

Yes, this:

refValue()[faceI] = vector::zero;

is the same as this:

refValue()[faceI] = vector(0,0,0);

Timucin,

Try this:

// Calculate and store face unit normals
const vectorField nf = patch().nf();

forAll(*this, faceI)
{
if (alpha[faceI] > 0.2)

Hi,

You could do the following:

forAll(*this, faceI)
{
if (alpha[faceI] > 0.2)
{
// Set face to fixedValue in all three directions
valueFraction()[faceI] = I;
