Hello,

I figured out that in the 1.6-ext version there is an inconsistency with the ILU smoother. In fact it is suggested to use it for an asymmetrix matrices but if you take a look to the code it is based on Cholesky Precon and not on ILU0 precon that should be the correct choice.
So I suggest to handle the Cholesky precon for both asymm and symm matrices as in the old 1.5-dev or something else.
Before the official patch if you need ILU smoother for asymm matrices change these lines in the iluSmoother.H in lduSolvers directory.

line 42
#include "ILU0.H"

line 60
ILU0 precon_;

Regards

Luca
