Hello, everyone! (:<br><br>Thank you very much, Barry, for your reply. I'll attempt to reconfigure PETSc with such external packages, as you told me, and see how it goes...<br><br>As for your questions, Lisandro:<br><br>
1) Incompressible bidimensional flow problem, via finite differences (Darcy's law) resulting in a pentadiagonal coefficient matrix;<br><br>2) Currently, I've been working with GMRES and LCD and now I intend to analyse in what way matrix reorderings routines affect the solving process (fill-in reduction, stability, number of iterations, etc);<br>
<br><div class="gmail_quote">I realize it's an easy problem and so matrix reorderings might not be too advantageous. But still, the main reason I want to pursue this it's because soon I'll be dealing with more complex nonlinear problems and when that time comes, I already plan to be familiarized with reorderings [:<br>
