how to turn off warning msg. when calling poisson library

[Chang_Lei]

I'm trying to turn off warning msg. when calling poisson library, as follow code:

call d_init_Helmholtz_3D(...,ipar,dpar,stat)

call d_commit_Helmholtz_3D(...,ipar,dpar,stat)

ipar(2)=0 !turn off warning msg

call d_Helmholtz_3D(...,ipar,dpar,stat)

call free_Helmholtz_3D(xhandle,yhandle,ipar,stat)

but find it doesn't work and the warning msg."The problem is degenerate up to rounding errors! The approximate solution that provides the minimal Eucledean (sic) norm of the residual will be computed..." is still printed on the screen.

Have I made mistake when set ipar(2) zeroor how can I turn off the warning msg.?
Thanks for your help.
Best regards.

Hi,

Actually, this message is not error, but warning. To stop printing warning setipar(3) = 0.
