Hi everybody, well the problem is this. I have to reach a value of Max in Skewness under 0.70 while using 5 layers of Inflation in my pipe for three meshes (750000 elements, 1.5 million and 3 millions of elements) but this has become a very hard task to achieve, not mentioning that my geometry is very small.

Can someone give me some advices? I've been changing the sizing values, applying inflation but nothing. I don't know if I'm doing something wrong here.

The features of my geometry are: D = 5.5 mm (Pipe and elbow 90). Length upstream is 15*D and downstream is 20*D.

Here's the mesh in the inlet face but is the same mesh through all the domain. I need to conserve the inflation with 5 layers and they ordered me to reach a Max in Skewness of 0.70 but I can't find the way to put it under that 0.79 or 0.78.

This is the picture for 0.75 million elements mesh, and I have to do the same for other meshes with more elements. Keeping the number of elements and reduce the Max value of Skewness.

what i mean is the pic of part whr skewness is high.
We need to bind that area!
why do u need sooooooooooooooo many elements?
