Hi Dune,<br><br>I am solving a Ax = b system with the dune CG solver. I somehow find that, the residual is very high (order of 10^38) & not zero! I run the solver with verbosity 2, & I find that the "defect" of the system is also non-zero & of very high order (~ 10^40).<br>
<br>Can someone please tell me the reason?<br><br>Regards,<br>Swayam<br>
