in my analysis momentem not converging properly but mass converging properly. please explain the physics in detail and how to avoid it

Hi,

Here is a detailed description of how to proceed:
1) Do more CFX tutorials
2) Read the CFX documentation
3) Do CFX training
4) Listen to your Fluid Mechanics lecturer
5) Actually explain what you are trying to do so we have some hope of helping you.

i got training from ansys for cfx and i know some about fluid mechanics.
i also try to understand thro cfx tutorial but failed

kindly can you explain why momentum not converging?

one more
support team in ansys told that you have to shift to transient analysis if this problem occur.

could explain why?

Hi,

See point 5 - please explain what you are trying to do.

i'm trying to do turbine side simulation in automobile turbocharger. (exhaust gas from engine is uses to compress the incoming air)
