Thanks Dr. Brown,<div> It works. I made a wrong comment command so that the code did not go through the compilation. So it gives the same error message since I ran the old version of execution file.</div><div> BTW, this ex29.c is a solver for 2D poisson equation. I wonder if there is any 3D Poisson Equation solver in PETSc code?</div>

A little problem comes up. I commented out VTK part, the code still has the same error message popping up. </blockquote></div><br></div><div>Well it can't be the same error message if that code isn't being executed. Send the whole error message.</div>
