We litteraly do not know where to start with your program as the turtorials are extremely vague.
For example, how do you make a simple wind tunnel? Where is the manual, the online version is spartan to say the least. We can't even get simple things to work, following the tutorials raises more questions than answers, the open pipe one for example assumes a certain level of knowledge.
We hope you can help, the program "Looks" great and the examples you show look very impressive, but you give absolutely no clue as to how to achieve these results.
