Dear all,nI am trying to solve a heat transfer problem in which i have used flue gases to heat air flowing inside tubes while the flue gas is flowing outside. However while initializing the solution, I am getting the error zone of type interior found between different fluids.nI am also not able to get proper results at outlet.nCan anyone help me to solve this problem?n

You need to put a wall between the two fluid zones: at present the shell side and tube side aren't separate. n

Hello sir. I would like to know that if I put a wall condition on the edges at which the fluids are interacting, will the flue gas still cause heat transfer to the fluid flowing in the pipe?n

[Rob]

Yes, a wall is a solid surface, heat will transfer through it based on the thickness you define: look at coupled walls in the User's Guide. n

Thank you for the valuable feedback. I'll definitely check it out and will update after that.n

Hello! Please i need help urgently. I started my work (a tutorial) with Ansys 2019 R3 using school computer, now i have transferred the file to my laptop and on my laptop i use Ansys 2020 R2 and 2021 R1. Each time i try to open the project on the project schematic, the file type does not show .wbpj files and so the project which is a .wbpj file does not show for me to open. I then select all file types from the file type and the .wbpj file pops up, but will not open. It shows unsupported file format. But when i close workbench and go to the file itself on the desktop and double click, it opens up immediately on my 2020 R2 version (although i am still confused why 2020 R2 is a default programme to open the file, why?). My main question now is, how do i open a .wbpj file on workbench after i have closed the workbench and my laptop? Also, on both the computer in my school and my laptop, 2020 R2 seems to be a default programme to open my Ansys file, how do i change it? See image below for my problem.nn
