Question about CFX-pre and CFX-post
Hi everyone,
May I ask if there's a way to set the volumetric flow speed through a surface as the inlet boundary condition in CFX-pre? And is there a way to calculate the volumetric flow speed through a surface from CFX-post? Best regards and many thanks, lnk |
Use a velocity boudnary condition, and use some CEL expressions to convert a volume flow rate to the veloicty.
To get the volume flow rate from an existing model use the function calculator in CFD-Post. |
if you have the inlet density you can use a mass flow inlet boundary

It is one of the options.

it's quiet easy! what is your problem? In cfd post you can do it by defining an expression: mass flow average@inlet |
