Hello every body, I am new Fluent user and I have a question on pressure and viscous drag resulting from flow inside a pipe with fixed area which should be:
pressure drag=0 , viscous drag > 0 in case of viscous flow .... when I used (hexahedron mesh) I found pressure drag =0, and viscous drag>0... BUT when I used (tetrahedron mesh) pressure drag was big value comparable to the viscous drag. can any one explain why this occurs when using tetrahedron elements??
