Fluent not reading interpolation .ip file correctly
 

Solved

I want to take a 2-D MatLab array and convert it to a 3-D interpolation (.ip) file, and then use this interpolation file to initialize my model.

There is a temperature distribution in X and Y, but not in Z. For a given X,Y position all Z positions will have the same value specified by the MatLab array.

Problem
When I interpolate my .ip file all the temperatures are 0 [K] not the temperature values in the .ip file

I am writing the .ip file according to the format specified in the fluent 19.1 Manual, shown at the bottom. I have included the .ip file without most of the points, and the message from the Fluent console.
If I remove the temperature limit, all the temperatures in my solid are 0 [K].
I have tried changing the "End of Binary Section 0" to be "End of Binary Section 0" " ... 1", "...2","...3".
I also tried using ")" to end each section, and the same console response is shown by fluent.

I am using Fluent 19.1 in double precision.

If you have any advice on the program or alternate ways to accomplish this I'm all ears.

Thanks,

I fixed this problem

I was using the wrong interpolation file version.

I had "5" written in the first line, but for ansys to interpret a text file it needs to be "3"
