<div dir="ltr">Hi, Omid, <div><br></div><div>It is normal. You should type the name of the session on the new graphical screen and 'enter'. Then you look at the terminal window in which you launched prenek. You will see new lines appears which demands you for furthur steps.
<div><br></div><div>Prenek and postx are a very old tools, and not graphically adapted in debian-based systems. You can install some libraries. It will fix several the problem, but not all. I think the best way is to write a script, which can be read by prenek. You can find the example ext_cyl, in which the file mkmesh is a simple example. It is not easy, and needs a lot of time to try and adjust by yourself, since the prenek is too difficult to be used graphically and interactively. Good luck! </div>
