How to export velocity profile and load it as inlet condition

      Dear friends, 


      I'm doing 2D-axisymmetric turbulent flow around a ramp 25°. For this I have to apply fully developed turbulent velocity profile at the inlet. First I run the simulation with a constant profile. 


      I want to extract the 2D velocity profile from  FLUENT calculation and load the velocity file as the input, but I don't know how to get the velocity file


      1-: Is it  possible to export a velocity profile at a  a simple line in a 2D model in CFD-Post?


      2-Is how this fully developed velocity profile can be correctly applied at inlet in next simulation?


      Thanks for your help!

      In Fluent Documentation look at the Profiles section, profiles can be written and read into Fluent. Note, you may need to correct the x & y positions unless the profile you're reading in is from the same geometric location. 


       


      As an aside, this is an open community moderated by ANSYS staff and volunteers. We also work in several timezones so please be patient: we also don't work weekends!

      You can do following:


       


      1/File>Write>Profile at the Inlet


      2/Read that back in other Case


       


      Here a tutorial

      It shows how to obtain profiles and use them for another case.


      It you think that the video is not helping then reformulate your question.
