Hello Matthew,<br>
<br>
Thank you for your help. I am sorry that I keep coming back with my error messages, but I reached a point that I don't know how to fix them, and I don't understand them easily.<br>
The list of errors is getting shorter, now I am getting the attached error messages </div>

Hello, <br>
I don't think that I set preallocation values when I created the matrix, would you please have look at my code. It is just the petsc related part from my code.<br>
