does anyone know what the coupled solver intend to? can someone explain when and why should i use this kind of solver? best regards, Ian

Hi Ian,

The coupled solver will solve all equations (conservation equations for mass, momentum and energy) simultaneously instead of sequentially (=segregated from one another). You should use the coupled solver when the velocity and pressure are strongly coupled (high pressures and high velocities). Very long calculation times can occur when you use the coupled solver. You can also find more information concerning the coupled solver in the User's Guide.

Thank you sandra, That was the exact answer i needed Cheers If you need something don't afraid to aks me.. Bye
