In my case, it is showing channel 395 directory not found.What to do then?
The dimensions of this rectangle are 4, 2, and 2. This could have been mentioned; at the minimum, the diagram could have been drawn proportionately.
Vertices numbers shown in the diagram and the coordinates shown in the file are confusing. For some vertices, their number in the diagram is also the length, but not for all vertices.You could have shown the diagram on the right side of the file (why should the text file be maximised?), with vertice coordinate triplet shown for each vertex.
Do you mean "when viewed in the negative y direction?"
why cant I copy from editor in windows to editor in ubuntu? Is it like I must open editor (from which I have to copy) in ubuntu only and then copy and paste?

In 3 min 26 sec it is stated that we have to delete some commands already excisting in block mesh dict n then copy some informations. but it is not clear how to open text file from which to be copied and from where to open it.
