Dear all,<br><br>I used "-snes_ksp_ew_conv" to inexactly solve the linear system with Petsc prescribed forcing term BUT I didn't catch any difference or improvement. I just screen out the "rtol" of KSP during<br>
SNES iteration and found out It is constant (1e-5) in both exact and inexact cases. Please let me know how I should implement "inexact" method in SNES and what is the relation between KSP tolerances and inexact setup?<br>
<br>Merry Xmas,<br>BehZad<br>
