Hello,

I need to have a transient velocity inlet. The inlet is transient and reads in wind data every 0.1s. The inlet is on the XZ plane and has 5 data points in the increasing z direction (wind increases in velocity as it gets further from the ground)


Screenshot of some of the data: https://imgur.com/E3geCi6

1 through 5 denotes increasing height


I have already tried this with 5 domains and 5 inlets for each height, but this creates instability and it would run better as a single domain with the velocity interpolated. What's the best way to do this

Anyone? I know the best approach is to write a UDF for this. I know how to interpolate values over distance, just not sure how to read in the data file into the udf and properly assign velocities at the right location and time
