I couldn’t find the custom wind profile in your project. Did you delete it? I tried to create the boundary condition that you specified and I had no problems.
The first step was to create an Excel file. It’s important to make sure that the decimal separator is the point. If you use the comma, SimScale won’t recognize it.
Then I saved the file in CSV (comma delimited) format.
Finally, I created the velocity inlet uploading the table.
You can access the updated project at this link.
Best,
