hi ... i have a case in which i have an outflow boundary on the outlet and it's done simulating... now i want to continue my other half of geometry on another case and need to export all data on the outlet surface and make it an input for the inlet of my new case ... for the simplicity of my case assume that i cut a cylinder in two cause i dont want to simulate the whole for reasons... first i simulate the first part then i want to export the case "1" outlet profiles to case 2 inlet. i want to export everything such as velocity profile and all turbulence profiles and anything that is needed to make the whole like i run them all together ... thanks ...

Try not to fall out of your chair....

File=>Write=>Profile

File=>Read=>Profile

srry i dont get it ... you mean if i just read the file it merges the profile to the inlet face automatically ? another question : i want to calculate pressure drop for a control valve. what kind of pressure should i consider total or static ... i saw somewhere they subtracted static outlet from total inlet ?tnx

No it's not automatic, I just mean that it is quite simple. You still have to set the profile as the new boundary condition. Go to your boundary conditions tab and at the velocity/pressure inlet, instead of choosing the default (usually constant) instead choose the profile that you have imported. Note you don't need separate profiles for each variable, you can export all variables for a surface, save it all to the same prof-name.prof and read all the variables in one go.

There are all sorts of pressure drops (static to static, static to dynamic, static to total and all permutations you can think of) and all carry some physical meaning to somebody. There's too many meanings to pressure drop that I can't really answer this. It depends what you are considering....
