Hi everyone

I have 3 turbines in a volume and wish to rotate them all. I have actually posted about this before but i have come across a couple of issues.

- when i specify my rotational axis origin for each of my walls, which point should i choose? Is it any point along the line which runs normal to the wall plane? (through the middle of it)

- when i am specifying my rotation axis origin for my fluid (water) do which point do i choose fort this? I have tried the point in the centre of the inlet face but this gives wrong results

Im pretty stuck here, so any help would be most appreciated

Cheers

rotation axis is vector quantity, when fluid zone rotated in center of coordinate, you need spesified what is axis, typicalluy in x, y and z, see your geometry to find its x,y, z direction ( if x your axis, you shoul type x=1,y=o and z=0, instead of case y as rotational axis, x=0,y=1 and z=o)
