I am simulating a flow in a pipe with pimpleFoam solver (imcompressible, newtonian and assuming laminar). Flow rate (m³/s) gives the following error:
(outlet flow rate- inlet flow rate ) / inlet flow rate = 0.07 >>> 7% > difference of 7% (I'm using adjustable time step and checkMesh returns "Mesh OK") Values: nu [ 0 2 -1 0 0 0 0 ] 6.85714e-06 diameter = 6mm of pipe max speed = 0.6 m/s Why?? Is this normal? Best Regards, Vitor Spadeto |
