Hi all, I have been working
 
Hi all,

I have been working at trying to get a new solver to work. The solver models a mixing compressible barotropic fluid with a functional form of viscosity. Anyway, I have my code compiling without error, yet it crashes with:

DILUPBiCG: Solving for rho, Initial residual = 1, Final residual =

Segmentation fault (core dumped)

I've tried different linear solver settings and it seems to be converging in all the variables. Any ideas would really be helpful. Do I have to recompile FOAM with a debug version?
