Basim Freegah

Dear Ahmed,

I think CFX is better to simulate axial flow pumps using Fluent, because there is moving part.

Regards,

ANSYS CFX is doing substantially better and more robust with any kind of turbomachinery flow (i.e. including pumps). ANSYS Fluent did never very well with moving interfaces between static and rotating subdomains.

Dr. Th. Frank.

Naseem Ahmad

Ansys CFX is good for turbomachinery components. So it is better to simulate an axial pump in CFX rather than fluent
