First, I print the matrix of the case cavity, mesh(4, 2, 1)

-0.000197 0.000079 0 0 0.000019 0 0 0
0.000079 -0.000182 0.000082 0 0 0.00002 0 0
0 0.000082 -0.000182 0.000079 0 0 0.00002 0
0 0 0.000079 -0.000099 0 0 0 0.000019
0.000019 0 0 0 -0.000099 0.000079 0 0
0 0.00002 0 0 0.000079 -0.000182 0.000082 0
0 0 0.00002 0 0 0.000082 -0.000182 0.000079
0 0 0 0.000019 0 0 0.000079 -0.000099

I use decoomposePar in case cavity to split mesh to processor0, processor1.
each proc store the 4*4 Ldu, the internelCoeffs and boundaryCoeffs.
In proc0, boundaryCoeffs is(of course store in vector),
0.000019 0 0 0
0 0.00002 0 0
0 0 0.00002 0
0 0 0 0.000019
In OF, it will add to source, but now I won't do this and I WANT get the original Matrix in each proc. For example, in proc0, I want get
-0.000197 0.000079 0 0 0.000019 0 0 0
0.000079 -0.000182 0.000082 0 0 0.00002 0 0
0 0.000082 -0.000182 0.000079 0 0 0.00002 0
0 0 0.000079 -0.000099 0 0 0 0.000019

But I cannot get the col of the elements in boundaryCoeffs.
HOW can I get the original coordinates of boundaryCoeffs in parallel?
