In a pervious post, you suggest me about scaling by keeping the dimensions for the roller in mm scale and scale in the fluent.
if I do so
big circle 300 mm small circle 100 mm and the difference between two big circles 5 micrometers. And patterns (H/W=30/40)
If i multiple these dimensions
And patterns 30 micrometer×1000
I am getting the same problem for meshing as you suggested to me.
And if only change micrometers dimension like pattern width and height (40*1000=40mm), (30*1000=30mm) and the gap between the circle (5*1000=5mm) and do not change other dimensions like big circle diameter = 300 mm and supported circle diameter = 100mm.
1. geometry, first of all, I can only make less no patterns. and how can I will be able to scale them?
2-second thing if I change the area between two concentric circles from 5micrometer to 5mm how I can I scale the area between two circles in fluent?
3. I need to mark the fluid region for as shown in the figure if I scale the mesh the radius of the circle and center will also change. so I need to mark the region for water how I will do this. I also divide the center and radius by 1000 and put these values for the marked region but it does not work for me. please suggest
