Parameters

au	Result for the first component of the vector.
av	Result for the first component of the vector.
aw	Result for the first component of the vector.
u	The first component of the vector.
v	The second component of the vector.
w	The third component of the vector.
coef	Coefficients.
msh	Mesh.
Xh	Function space \( X_h \). Compute the product.
w	Vector of size (lx,ly,lz,nelv).
u	Vector of size (lx,ly,lz,nelv).
coef	Coefficients.
msh	Mesh.
Xh	Function space \( X_h \).

Note

Since this is a performance-crtical routine, it is implemented in several kernels corresponding to different polynmial orders.
