Hello,

I'm using s_Helmholtz_2D routine to solve my Poisson equation. I specify Neumann boundary conditions for all boundaries and receive this warning:

MKL POISSON LIBRARY WARNING:
The problem is degenerate up to rounding errors! The approximate solution
that provides the minimal Euclidean norm of the solution will be computed...

Yes, I totally understand that and all works fine. So, is there a way do disable this warning? It's just spamming output of my utility.

Hi,

Try to set ipar[2]=0.

With best regards,

It works! Thanks a lot!

And by the way: I wouldn't have asked such a simple question if there was convenient search on the reference, really.

You are welcome! :)

The instructions given by Alexander Kalinkin are for C++ or a zero based language. For fortran you need to set ipar(3) =0.
