Deformed Meshing
 

Hi, Am dealing with a U-tube problem, the aspect ratio(length/diameter) for which is too high. So in the model I have to link 4 faces(2 end faces and 2 faces midway). After linking I do meshing for the faces, for the first face the meshing is OK, however it gets deformed from one face to another as I proceed along the tube. Please help.

thanks in advance!!!
