Air intake connection solver probleme CFX
 

Mesh is available in .cgns format. In CFX pre it is imported and set the boundary conditions. But after few iteration solution is stopped giving info that overflow occur.
Could you please give some idea how to overcome from this problem.
Thanks

I should write an FAQ on this, been asked so many times....

The overflow error means your simulation has diverged. Need to improve the numerical stability. Try smaller timesteps, lower order discretisation, double precision numerics, improve mesh quality, simpler physics, better initial conditions.
