<div dir="ltr">Dear all,<div><br></div><div>I'm trying to solve a linear system with petsc ksp solver. But after I called the kspsolve routine, I always got the "Vec entry at local location 0 is not-a-number or infinite at end of function" errors below. I checked the matrix and the vectors, and they are all numbers (and zeros). Is this a bug or I miss something? Thank you very much in advance!</div><div><br></div><div>
