Forum ModeratorWhat have you set the various sizing options as? Why do you need a butterfly mesh?Â

SubscriberThe model is of CFD and it is hollow cylinder and fluid part is divided into 5 parts to creat uniform hexahedral meshing. I had done automatic method for the whole body and edge sizing of the edges dividing the fluid domain by choosing number of division as 100. And the result I am getting is in one sliced part of fluid domain long elements are formed instead of small ones. So how to resolve this or this can be solved as I am solving it for natural convection process when the tube is heated with a constant heat flux and nusselt number is to be calculatedÂ

Forum ModeratorI'm aware of what a O-grid/butterfly mesh is, I'm just wondering why anyone would bother doing it now.Â
You've set a cell size on the centre body. Have you set any sizing on the surrounding bodies? I'd favour using a single volume, inflate the boundary (read up on Sweep method) and pave the end face. It's far quicker and will likely result in a higher quality mesh.Â

SubscriberHey Rob
Can you suggest me some methods with which I can increase element quality aspect ratio skewness without opting for o-grid technique to do a structured mesh.

Forum ModeratorOn a circle? No, there's a reason for pave mesh and decomposition.Â

SubscriberYes on the circle so that I can get a structured mesh without going for o gird method

Forum ModeratorHow do you propose putting a square into a circle without either decomposition or very skew cells?Â
