I call out flair simply by typing “flair” in my WSL Ubuntu terminal and used Xming to render flair.
I load my input file first and created then saved the project. I started the run and got these errors.
Then, just to make sure the problem is not in my input file, I created a project simply used the build-in Basic project and followed each step in the Youtube video on Flair’s tutorial. Unfortunately, same errors pop up.
I started Flair with the command you wrote then ran the input I wrote, which is a paraphrase on the example in the FLUKA manual. Here’s what I got from the flair.log.
