Hi Jed,<br>
<br>
I think I understand what you mean. Are you saying that I have 2
separate nxn matrix to solve.<br>
<br>
I combine them to form a 2n x 2n matrix and solve. I think it will
also improve the scalability with regards to MPI too.<br>
<br>
Is that so? <br>

<div>Sure, interlace the x and y degrees of freedom and assemble
the matrix with x equations in the even row/column numbers and
y equations in the odd row/column numbers.</div>
<div><br>
</div>
<div>Note that the equations are not decoupled for some boundary
conditions (e.g. slip on a curved surface or free surface).</div>
