Hi there,

Well i'm running a compressible flow. I;v been lowering my under relaxation factor for pressure, and this warning keeps coming up.

Warning #072, Pressure initialization failure, pressure will be scaled.

I thought it had to do with the under-relaxtion factor, but when i modify it , this warning keeps appering.

Somebody knows how to fix it or if i can just ignore it? The problem does converge.

Thanks

You can just ignore it. Obviously, the pressure field was not initialized correctly. Maybe you should have used manual initialization instead of code initialization...

This problem should not bother you as this only appears at the zeroth iteration when STAR-CD tries to initialise the flow field by solving potential equation. It does not afftect your result and indeed in certain situation, you are better off to turn off code initialisation.
