  i'm using a 2D simulation in order to study the flow of a non-Newtonian fluide inside a pipe , i have changed the division of the cells , but it has not given comparable results yet . i do not know the reaso . Does anyone know how to divide geometry and messh in a good way ? knowing ( L=1.2) and (D=0.02) , i have tried several division as ( 50*750) , (50*500) , ( 100*1000) , (100*750) , who has an idea how to choose the division accurately ?

  Are these dimensions (L*D) or (D*L)?
  How far off are you from expected results? How do you know this is mesh related?
