split numerator over two lines


you could use an array environment for the numerator.


Yes, but i thought there is a more elegant solution. Besides, the equation is a part of
\begin{subequations}
\begin{align}
.... %subequations here
\vec{u}_{i,j,k+1/2} &= \left(\frac{u_{i-1/2,j,k}+u_{i+1/2,j,k}+u_{i-1/2,j,k+1}+u_{i+1/2,j,k ...

split numerator over two lines

Hello,
I have a long fraction that doesn't fit on a page:

\vec{u}_{i+1/2,j,k} = \left(u_{i+1/2,j,k}, \frac{v_{i,j-1/2,k}+v_{i,j+1/2,k}+v_{i+1,j-1/2,k}+v_{i+1,j+1/2,k}}{4}, \frac{w_{i,j,k-1/2}+w_{i,j,k+1/2}+w_{i+1,j,k-1/2}+w_{i+1,j,k+1/2}}{4} \right) ,

What I would like to do, is to split the ...
