The solution contains 1 non-physical point

jwang1_09 · December 17, 2013, 08:32

Hello,everyone.

I want to use my mesh to compute the ONERAM6 wing in the NAVIER_STOKES physical governing equations. I chang the options in 'turb_ONERAM6.cfg':KIND_TURB_MODEL = NONE. But after some iterations, it always appears that 'The solution contains 1 non-physical points'.
I can not understand this, could you help me?

This is a warning message that we have removed in the latest version of the code. It only means that the solution update have produced points with negative density. This is not a critical situation and sometimes the solver is able to recover from this problem (reducing the CFL and disabling the MG should help).

Best,
Francisco
