I am new to programming in OpenFoam, so any thoughts would be helpful. I want to assemble a sparse matrix at every centroid. Let's call the matrix A Entries of the matrix will be functions of flow variables like density, pressure etc. I can't seem to find a suitable constructor. Could someone help Thanks Srinath
