示例1: ePrev
// Test face for (almost) convexeness. Allows certain convexity before
// complaining.
// For every two consecutive edges calculate the normal. If it differs too
// much from the average face normal complain.
bool Foam::combineFaces::convexFace
(
const scalar minConcaveCos,
const pointField& points,
const face& f
)
{
// Get outwards pointing normal of f.
vector n = f.normal(points);
n /= mag(n);
// Get edge from f[0] to f[size-1];
vector ePrev(points[f.first()] - points[f.last()]);
scalar magEPrev = mag(ePrev);
ePrev /= magEPrev + VSMALL;
forAll(f, fp0)

// Normalized vector between two consecutive points
