<div dir="ltr">Hi Jacopo,<div><br></div><div>I'm not able to look at your files at this moment, but I do have a quick suggestion. Nek is normally pretty flexible when it comes to the .rea formatting except for boundary conditions and curve sides. I would suggest carefully studying the format of the base3.rea file and make sure the formatting you are using to create pipe.rea is the same.</div>
