problem with importing and exporting profile BC
 
I have a problem for both exporting and importing profile boundary conditions :

- First I'd like to export a Total pressure profile boundary condition. But when I try CFX tells me that the variable Total Temperature does not exist. In my problem rho and cp are constant so the total temperature is the same as static temperature (it's written in CFX manual). So CFX should have no problem. Why is that?

- So instead I exported a velocity profile boundary condition (is it as good as a total pressure profile BC ?). Now I need to know how to be sure that this profile is gonna fit with the plane of the new geometry where I'm gonna import it (because the global plane of the two geometries are different and when I import and initialize the profile, a new plane (probably the reference plane of the geometry from wich I imported the profile) appears)

Thank you in advance.

I just realized that I misplaced one word in my question. Sorry, I am tired and English is not my mothertongue !

"Now I need to know how to be sure that this profile is gonna fit with the COORD FRAME of the new geometry where I'm gonna import it (because the global COORD FRAME of the two geometries are different and when I import and initialize the profile, a new COORD FRAME (probably the reference COORD FRAME of the geometry from wich I imported the profile) appears)"

Hi Gui,

You can define a local coordinate system in Pre and use it with the boundary condition where the profile is to be applied.
