[ANSYS Meshing] Skewed mesh

mwood · February 18, 2013, 12:32

Hello

I am using Fluent 14.0.
I have a setup that involves pipes meeting a chamber at a 90 degree angle. I am getting highly skewed grid at the ring where they meet.
Does any one know how I would fix this?

Thanks

So these show the meshed chamber with the pipes and then where the mesh is highly skewed.

Go back to designmodeler, see where you have the intersection of the pipes with the square, make a slice there, the slice will result in multiple part, select them all, right click and select FORM NEW PART. now back to the mesher, select each part, right button click, insert multizone. do that for all the part. I'm not very proficient with ansys meshing but i saw a lot of thread discussing about this method. try it . moreover i can pass you the tutorials they are available in the customer portal
