Hello all,

I am trying to incorporate a transient boundary condition in fluent. I am doing this by defining a transient profile in tabular format by following the fluent user guide. The table is saved in text format. I am trying to read it into fluent by using the read-transient-table command. I have saved the file in the right directory. However, I keep getting a file not found error. Can someone let me know what I need to do to rectify this?

Thanks!

Hello,

Have you watched this video on youtube and try this for your modeling purpose.

Thanks Karthik. I did watch this video. However, Fluent for some reason does not recognize the text file format. I worked my way around this by writing the boundary conditions file to the folder. Then deleted everything in it and wrote the transient table as shown in the above video and then read it into Fluent. that worked for me. I am not sure if there is a more direct way to do it.

Check the headers & white-space characters too. Are there any spaces in the file name or directory structure?

I am using the transient table to define the boundary conditions. Go through the below link for details on how to setup the transient table.

I have a question to ask. I am trying to read a transient table into Ansys fluent. I am using the TUI command of "file", "read- transient-table". However, when I try and read the file it says data not complete. What could be the issue?

How does the format compare to the example in the documentation?

Hello Rob,

 I have resolved the issue.I am using a data input as a .txt file. I found out that when entering the number of variables, you have to take into account any spaces above the numbers.

If you have any spaces, ANSYS seems to count it as additional variables. This is what made the solver say DATA incomplete. I hope this helps anyone else having a similar issue.

Thanks for posting. It's possible you have/has white space characters, that's often caused by Windows>Linux and when copying from the Ansys documentation (HTML or pdf). Either way it's fixed.
