[petsc-users] ERROR Arguments are incompatible in MatSetValues()

[PEREZ CERQUERA MANUEL RICARDO]

Hi all,

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
