Hi all,<br>
<br>
I have a petsc code which works for a certain number of unknowns, I mean it works with a matrix of 12000X 12000 elements, then when I increase the Number of unknowns to 25000 X 25000 I got this error at certain point in one of the MatSetValues() function, I don't know which are the possible causes, I have enough memory to handle it. Could you give me some ideas of whats going on? . Thanks<br>
