Hi.I am new to openfoam so i apologise if this is a trivial problem.I cant seem to figure out why my mesh looks like this and isnt uniform for both the blocks.I have attached the mesh image.Here is my blockmesh file:

Hi!

Your blocking is bad. If it is a pipe try to use one wedge block. You can find more about it here:

Thank you for the reply sir.I initially tried using a single wedge block.However i was not able to get the curve on the top edge even after a lot of tries.I defined the arc in the edge section too.Can you guide me how to get the curve edge usign a single wedge block.
