Hi,

I have edited the Helmholtz with Flow Tutorial geometry and used the L-Vel fluids model rather than SST. I would like to model Mach=0.3 flow, but I get the error:

There are 11923 degrees of freedom giving NaN/Inf in the vector for the variable comp1.uPlus. at coordinates: (0.265158,0.0136567,0.0745744), (0.265875,0.0149679,0.0745744)...

I have checked the boundary conditions, mesh and air properties as suggested in other threads, but I still get an error.

Any suggestions would be much appreciated.

Thanks
