How to print out a real matrix for discretised equation ?

mxylondon · February 20, 2013, 03:28

Hi, guys.

As we know, in OpenFOAM, those non-zero matrix coefficients for discretised equation are stored in three arrays.
But it's not comfortable to see the structure of the matrix. So, is that OK to print out them together with zero elements in a real matrix form?

Thank you very much!
